The apparatus uses an optical component mount that includes a housing consisting of a single rail mount configured to mechanically couple to a portion of a rail for supporting the optical component mount on a rail. The housing also has an optical component dock configured to support an optical component in a manner that defines an optical axis. The rail mount and the optical component dock are configured to make the optical axis substantially parallel with a longitudinal axis of the rail.

Description

FIELD

This disclosure relates generally to optical systems, and in particular, to a system and method for mounting and aligning optical components using single-rail mounting.

BACKGROUND

Optical measurement systems are typically employed to measure certain properties or characteristics of one or more specimens. In implementing such measurements, optical measurement systems employ various optical components arranged in a particular manner in order to effectuate the intended measurement on the one or more specimens. Such optical components include, but are not limited to, light sources, filters, lenses, mirrors, spatial filters, modulators, choppers, collimators, detectors, diffusers, fiber optics, prisms, and others.

Optical components of such an optical measurement system are typically mounted on an optical table using various types of fixed mounts. Such fixed optical component mounts are secured to separate posts that are, in turn, secured to an optical table. With individual components being on separate posts, optical alignment typically requires significant effort to properly adjust the position and orientation of each individual mount. For instance, considerable effort is often made to properly orient each optical component so that its optic surface faces an incoming beam substantially perpendicular. Further, substantial effort is often employed in aligning optical components concentric with each other (e.g., so that their optical axes are substantially aligned).

In many systems, optical alignment is often performed with a live beam. This method of optical system setup entails relying on a live beam spot image to properly align the optics of the system. Again, such alignment method involves considerable effort, typically repeated, and time consuming to properly position and orient optical components so that their optical surfaces are substantially perpendicular to the incoming beam and concentric with each other.

DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS

FIG. 1A illustrates a perspective view of an exemplary apparatus 100 for mounting and aligning optical components in accordance with an aspect of the disclosure. In summary, the apparatus 100 comprises a plurality of optical component mounts to which a plurality of optical components may be mounted, respectively. The optical component mounts are secured onto a single rail. The securing of the optical component mounts onto the single rail ensures that the optical axes of the optical components are substantially aligned. That is, the alignment of the optical axes may entail the optical components being substantially concentric with each other, and/or the optical surface of each of the components being substantially perpendicular to the transmitted or received light beam.

More specifically, the apparatus 100 comprises a plurality of optical component mounts 120a, 120b, 120c, and 120d. Although in this example, the apparatus 100 comprises four (4) optical component mounts, it shall be understood that the apparatus may have any number of optical component mount(s). The apparatus 100 further comprises a single rail 110 to which the optical components mounts are securely mounted. In this example, the rail 110 has a semi-circular cross-section with a flat surface 112. As discussed further herein, the flat surface 112 is used in connection with a locking mechanism to secure the optical component mounts 120a, 120b, 120c, and 120d on the rail 110. However, it shall be understood that that the rail 110 may be configured with a cross-section of any shape.

More specifically, each optical component mount (120a, 120b, 120c, and 120d) comprises a housing (122a, 122b, 122c, and 122d) that consists of a single rail mount (124a, 124b, 124c, and 124d) mechanically coupled to a portion of the rail 110 for supporting the optical component mount on the rail. In the exemplary embodiment, the rail mount (124a, 124b, 124c, and 124d) is configured as a hole through the housing (122a, 122b, 122c, and 122d). It shall be understood that the rail mount may be configured in many different manners.

Each optical component mount (120a, 120b, 120c, and 120d) includes a locking mechanism (128a/130a, 128b/130b, 128c/130c, and 128d/130d) for securely locking the rail 110 to the rail mount (124a, 124b, 124c, and 124d). In the exemplary embodiment, the locking mechanism comprises a countersink threaded hole (128a, 128b, 128c, and 128d) extending from a side wall of the housing (122a, 122b, 122c, and 122d) to the hole (124a, 124b, 124c, and 124d). Further, in accordance with the exemplary embodiment, the locking mechanism comprises a lock screw (130a, 130b, 130c, and 130d) threaded into the countersink hole (128a, 128b, 128c, and 128d). As discussed in more detail further herein, the tail end of the locking screw (130a, 130b, 130c, and 130d) makes contact with the flat surface 112 to urge the rail 110 against the internal wall of the hole (124a, 124b, 124c, and 124d) to effectuate the secure mounting of the optical component mount (120a, 120b, 120c, and 120d) to the rail 110.

Each of the housing (122a, 122b, 122c, and 122d) of the optical component mounts (120a, 120b, 120c, and 120d) further includes an optical component dock (126a, 126b, 126c, and 126d). Each of the optical component dock (126a, 126b, 126c, and 126d) is configured to securely and coaxially receive an optical component (not shown in FIG. 1A) in a manner that defines an optical axis (132a, 132b, 132c, and 132d) substantially parallel with a longitudinal axis of the rail 110. In this example, each of the optical component dock (126a, 126b, 126c, and 126d) is configured as a threaded hole for mating with external threads of a corresponding optical component. It shall be understood that the optical component dock may be configured in different manners for securely receiving an optical component.

The distance and position of the center of the thru-hole (124a, 124b, 124c, and 124d) with respect to the center of the optical component dock (126a, 126b, 126c, and 126d) are accurately controlled to ensure that the optical axes (132a, 132b, 132c, and 132d) of the optical components mounted on the mounts (120a, 120b, 120c, and 120d) are substantially aligned (i.e., substantially collinear). This ensures that the optical components are substantially concentric with each other, and that the optical surface of each of the components is substantially perpendicular to the propagating light beam. The locking screws (130a, 130b, 130c, and 130d), whose ends contact the flat portion 112 of the single rail 110 via the countersink holes (128a, 128b, 128c, and 128d) ensure that the position of the optical component mounts (120a, 120b, 120c, and 120d) with respect to the single rail 110 is secured and locked.

The apparatus 100 further comprises a base 150 for mounting the apparatus on an optical table (not shown). In this regard, the base 150 may comprise a slot 152 to receive one or more threaded screws for securing the base onto the optical table.

Additionally, the apparatus 100 further comprises a telescopic assembly 160 securely mounted on the base 150. The telescopic assembly 160 includes a bore 162 through which a telescopic mount 164 extends and slides coaxially along a longitudinal axis of the bore. The telescopic mount 164 is further configured to rotate coaxially within the bore 162. The telescopic assembly 160 further comprises a locking knob 166 for locking the telescopic mount 164 within the bore 162 in a desired vertical and angular position. The telescopic mount 164 further includes a mounting post 168 extending vertically and coaxially above the telescopic mount. The mounting post 168 is configured to be received through another hole at a bottom side of optical component mount 120c, in this example. A user may adjust the vertical and angular position of the telescopic mount 164 within the bore 162 to vertically and angularly position the optical component mounts 120a, 120b, 120c, and 120d as desired.

FIG. 1B illustrates a perspective view of the exemplary apparatus 100 including a couple of optical components mounted thereon in accordance with another aspect of the disclosure. In this example, the apparatus 100 further comprises a lens 180 securely and coaxially mounted in the optical component dock 126c of optical component mount 120c. Additionally, in this example, the apparatus 100 comprises a camera 190 securely and coaxially mounted in the optical component dock 126d of optical component mount 120d. Although in this example, the lens 180 and camera 190 are examples of optical components that may be mounted to the apparatus 100, it shall be understood that other types of optical components may be mounted to the apparatus as well.

Because the optical component mounts 120c and 120d are secured onto the common single rail 110, and the distance and position of the centers of the thru-holes 124c and 124d with respect to the centers of the optical component docks 126c and 126d are accurately controlled, the light beam (shown as an alternating dash-dot arrow line) propagates substantially through the optical axes 132c and 132d of the lens 180 and camera 190. Again, this ensures proper optical alignment between the components 180 and 190 to ensure accurate and precise optical processing, detection and measurement.

FIG. 2A illustrates a perspective view of another exemplary apparatus 200 that includes at least one optical component (a “junction optical component,” hereinafter) configured to transmit and/or receive light beams to and from different directions. In summary, the apparatus 200 comprises optical component mounts mounted respectively onto a plurality of rails or rail sections that intersect at the junction optical component. As some examples, junction optical component may be configured to split a light beam, combine light beams, change light beam direction, or transmit light beams in different directions.

More specifically, the apparatus 200 comprises a plurality of optical component mounts 220a, 220b, 220c, and 220d similar to optical component mounts 120a, 120b, 120c, and 120d of apparatus 100, previously discussed. That is, each optical component mount (220a, 220b, 220c, and 220d) comprises a housing (222a, 222b, 222c, and 222d) that consists of a single rail mount (224a, 224b, 224c, and 124d) (e.g., a thru-hole) mechanically coupled to a portion of a rail or rail section (210a, 210b, 210c, and 210d).

In this example, each rail or rail section (210a, 210b, 210c, and 210d) has a semi-circular cross-section with a flat surface (212a, 212b, 212c, and 212d). Similar to the previous embodiment, the flat surface (212a, 212b, 212c, and 212d) is used in connection with a locking mechanism to secure the optical component mount (220a, 220b, 220c, and 220d) to the rail or rail section (210a, 210b, 210c, and 210d). However, it shall be understood that that the rail (210a, 210b, 210c, and 210d) may be configured with a cross-section of any shape.

Each optical component mount (222a, 222b, 222c, and 222d) includes a locking mechanism (228a/230a, 228b/230b, 228c/230c, and 228d/230d) for securely locking the rail or rail section (210a, 210b, 210c, and 210d) to the rail mount (224a, 224b, 224c, and 224d). In the exemplary embodiment, the locking mechanism comprises a countersink threaded hole (228a, 228b, 228c, and 228d) extending from a side wall of the housing (222a, 222b, 222c, and 222d) to the hole (224a, 224b, 224c, and 224d). Further, in accordance with the exemplary embodiment, the locking mechanism comprises a lock screw (230a, 230b, 230c, and 230d) threaded into the countersink hole (228a, 228b, 228c, and 228d). As discussed in more detail further herein, the tail end of the locking screw (230a, 230b, 230c, and 230d) makes contact with the flat surface (212a, 212b, 212c, and 212d) to urge the rail or rail section (210a, 210b, 210c, and 210d) against the internal wall of the hole (224a, 224b, 224c, and 224d) to effectuate the secure mounting of the optical component mount (220a, 220b, 220c, and 220d) to the rail or rail section (210a, 210b, 210c, and 210d).

Each of the housing (222a, 222b, 222c, and 222d) of the optical component mounts (220a, 220b, 220c, and 220d) further includes an optical component dock (226a, 226b, 226c, and 226d). Each of the optical component dock (226a, 226b, 226c, and 226d) is configured to securely and coaxially receive an optical component (not shown) in a manner that defines an optical axis (232a, 232b, 232c, and 232d) substantially parallel with a longitudinal axis of the rail or rail section (210a, 210b, 210c, and 210d). In this example, each of the optical component dock (226a, 226b, 226c, and 226d) is configured as a threaded hole for mating with external threads of a corresponding optical component. It shall be understood that the optical component dock may be configured in different manners for securely receiving an optical component.

In apparatus 200, the rails or rail sections 210a, 210b, 210c, and 210d all intersect at a junction optical component mount 240 for a junction optical component 280. The junction optical mount 240 includes holes to receive respective portions the rails or rail sections 210a, 210b, 210c, and 210d, the holes being positioned to ensure substantial alignment (i.e., collinear) of a set of optical axes 282a, 282b, 282c, 282d of the junction optical component 280 with the optical axes 232a, 232b, 232c, 232d of the optical component mounts 220a, 220b, 220c, and 220d, respectively. Although in this example, the longitudinal axes of the rail or rail sections 210a, 210b, 210c, and 210d intersect each other at right angles (e.g., 90 degrees), it shall be understood that they may intersect each other at angles other than right angles.

The apparatus 200 further comprises a base 250 for mounting the apparatus on an optical table (not shown). In this regard, the base 250 may comprise a slot 252 to receive one or more threaded screws for securing the base onto the optical table.

Additionally, the apparatus 200 further comprises a telescopic assembly 260 securely mounted on the base 260. The telescopic assembly 260 includes a bore 262 through which a telescopic mount 264 extends and slides coaxially along a longitudinal axis of the bore. The telescopic mount 264 is further configured to rotate coaxially within the bore 262. The telescopic assembly 260 further comprises a locking knob 266 for locking the telescopic mount 264 within the bore 262 in a desired vertical and angular position. The telescopic mount 264 further includes a mounting post (not shown, but similar to mounting post 168) extending vertically and coaxially above the telescopic mount. The mounting post is configured to be received through a bottom hole of the junction optical mount 240. A user may adjust the vertical and angular position of the telescopic mount 264 within the bore 262 to vertically and angularly position the optical component mounts 220a, 220b, 220c, and 220d and junction optical mount 240 as desired.

The junction optical component 280 may be configured to split a light beam, combine light beams, change light beam direction, transmit light beams in different directions, or perform other optic functions with respect to multiple direction light beams. As examples, the junction optical component 280 may be a prism configured to split incoming light beam received from an optical component mounted on optical component mount 220a and transmit the split light beams to optical components mounted on optical component mounts 220b and 220c, respectively. As another example, the junction optical component 280 may be an optical combiner configured to combine separate light beams from optical components mounted on optical component mounts 220a and 220d, and transmit the combined light beam to an optical component mounted on optical component mount 220b.

As other examples, the junction optical component 280 may be a mirror configured to receive a light beam from an optical component mounted on optical component mount 220a, and redirect the light beam to an optical component mounted on optical component mount 220b. As still another example, the junction optical component 280 may be a laser source including optics for generating multiple light beams and directing them to two or more optical components mounted on two or more of the optical component mounts 220a, 220b, 220c, and 220d. The junction optical component 280 may be other types of optical devices different than the aforementioned examples.

FIG. 2B illustrates a top view of the apparatus 200 with the junction optical component 280 removed and the top wall of the junction optical component mount 240 partially transparent to illustrate internal components of the mount. As illustrated, the rail sections 210a and 210c are sections of a single rail; whereas, the rails 210d and 210b are separate from each other.

The junction optical component mount 240 includes a locking screw 244a mounted through a side of the mount and threaded into a bore 242a attached to the rail 210d. This secures the rail 210d onto the junction optical component mount 240. The junction optical component mount 240 also includes a locking screw 244b mounted through the side of the mount and threaded into a bore 242b attached to the rail 210b. This secures the rail 210b onto the junction optical component mount 240. Further, the junction optical component mount 240 includes a locking screw 244c mounted through another side of the mount and threaded into a bore 242c attached to the rail 210b/210c. This secures the rail 210b/210c onto the junction optical component mount 240.

Additionally, the junction optical component mount 240 comprises an alignment hole 248 to receive an alignment post (not shown) extending downward from a bottom of the junction optical component 280. In addition, the junction optical component mount 240 comprises a plurality of threaded screws 246 for securing the junction optical component 280 onto the mount 240.

FIG. 3 illustrates a perspective view of another exemplary apparatus 300 for mounting and aligning optical components in accordance with another aspect of the disclosure. The apparatus 300 is similar to that of apparatus 100, except that the optical component mounts have docks of different diameters to accommodate differently-sized optical components. Additionally, the apparatus 300 includes link blocks and multiple rails in order to substantially align the optical axes of the different-size optical components.

In particular, the apparatus 300 comprises a plurality of optical component mounts 320a, 320b, 320c, and 320d. Although in this example, the apparatus 300 comprises four (4) optical component mounts, it shall be understood that the apparatus may have any number of optical component mount(s). The apparatus 300 further comprises rails 310a, 310b, 310c, and 310d to which the optical components mounts 320a, 320b, 320c, and 320d are securely mounted.
