Claims
- 1. A magnification loupe carried by spectacles having a pair of lenses comprising:an eyepiece lens housing having at least one eyepiece lens mounted therein, said eyepiece lens housing being smaller than a lens of said spectacles and including threads thereon; an objective lens housing having at least one objective lens mounted therein and including a pin aperture and a pin received in said pin aperture engaging said threads such that said objective lens housing is rotatably adjustable relative to said eyepiece lens housing to enable a distance between said eyepiece lens housing and said objective lens housing to be varied.
- 2. A magnification loupe according to claims, wherein said objective lens housing is removable to permit substitution by a second objective lens housing carrying an objective lens of different magnification.
- 3. A magnification loupe carried by spectacles having a pair of lenses comprising:an eyepiece lens housing having at least one eyepiece lens mounted therein, said eyepiece lens housing being smaller than a lens of said spectacles and including threads thereon; an objective lens housing having at least one objective lens mounted therein and including a pin aperture; and adjustable means for moving said objective lens housing relative to said eyepiece lens housing to vary a distance between said objective lens housing and said eyepiece lens housing; an optic element disposed on said loupe for increasing a light path length between said at least one objective lens and said at least one eyepiece lens; wherein said adjustable means includes a pin aperture in said objective lens housing, threads on said eyepiece lens housing opposing said pin aperture, and a pin received in said pin aperture for engaging said threads.
- 4. A magnification loupe carried by spectacles having a pair of lenses comprising:an eyepiece lens housing having at least one eyepiece lens mounted therein, said eyepiece lens housing being smaller than a lens of said spectacles and including threads thereon; an objective lens housing having at least one objective lens mounted therein and including a pin aperture; and adjustable means for moving said objective lens housing relative to said eyepiece lens housing to vary a distance between said objective lens housing and said eyepiece lens housing; an optic element disposed on said loupe for increasing a light path length between said at least one objective lens and said at least one eyepiece lens, wherein said optic element is a roof-penchan prism; and wherein said adjustable means includes a pin aperture in said objective lens housing, threads on said eyepiece lens housing opposing said pin aperture, and a pin received in said pin aperture for engaging said threads.
- 5. A magnification loupe carried by spectacles having a pair of lenses comprising:an eyepiece lens housing having at least one eyepiece lens mounted therein, said eyepiece lens housing being smaller than a lens of said spectacles and including threads thereon; an objective lens housing having at least one objective lens mounted therein and including a pin aperture; and adjustable means for moving said objective lens housing relative to said eyepiece lens housing to vary a distance between said objective lens housing and said eyepiece lens housing; an optic element disposed on said loupe for increasing a light path length between said at least one objective lens and said at least one eyepiece lens wherein the optic element is a roof-penchan prism that includes two prisms separated by a spacer having an aperture centered on an optical axis of said loop; and wherein said adjustable means includes a pin aperture in said objective lens housing, threads on the surface of said eyepiece lens housing opposing said pin aperture, and a pin received in said pin aperture for engaging said threads.
