OPTICAL LENS ASSEMBLY AND ELECTRONIC DEVICE

BACKGROUND
Technical Field

The present disclosure relates to an optical lens assembly and an electronic device. More particularly, the present disclosure relates to an optical lens assembly and an electronic device that include a blue-glass lens element and can be used to filter out the near-infrared light.

Description of Related Art

In current, the method to filter out the near-infrared light of the optical lens assembly is to arrange a blue glass plate having a near-infrared light filtering coating membrane on the surface thereof in front of the image sensor so as to serve as a filter. The combined use of the near-infrared light filtering coating membrane and the blue glass material can reduce the interference in the optical imaging caused by the near-infrared light. However, when the near-infrared light is filtered out, the visible light will reflect back and forth among the near-infrared light filtering coating membrane, the blue glass plate and the image sensor. Further, because the reflected light incidents in the image sensor multiple times, the petal-shaped flares that are difficult to eliminate will be generated, resulting in a significant reduction in the imaging quality.

Accordingly, the blue glass plate and the near-infrared light filtering coating membrane disposed on the surface thereof is an important arrangement that cannot be changed easily, and thus if the shortcoming caused by the aforementioned arrangement wants to be solved, a new arrangement for filtering the near-infrared light needs to be developed.

The long-wavelength filtering coating membrane can be further disposed on the object-side surface or the image-side surface of the long-wavelength absorbing lens element, so that the long-wavelength filtering lens element and the long-wavelength absorbing lens element can be the same optical lens element.

The long-wavelength filtering coating membrane disposed on the object-side surface and the image-side surface of the optical lens element means the long-wavelength filtering coating membrane is directly or indirectly disposed on the object-side surface and the image-side surface of the optical lens element, wherein the indirect disposition means that there are other kinds of coating membranes (such as anti-reflecting membranes) or other arrangements (such as coating layers or other materials) between the long-wavelength filtering coating membrane and the surface of the optical lens element. The arranging position of the long-wavelength filtering coating membrane also can be the object-side surface and the image-side surface of other optical elements, and the optical elements that can be arranged therewith are the flat glass, the protective glass, the plastic plate, the glass plate, the reflective element, etc. The filtering coating membrane disposed on other elements can enhance the complete filtering effect of the insufficient wavelength bands, so that the coating membrane formed on the surface of the optical lens element can be used to filter the light with a specific wavelength band so as to reduce the number of layers and the thickness.

In the layer composition of the long-wavelength filtering coating membrane of the present disclosure, the long-wavelength filtering coating membrane can include at least one membrane layer.

The long-wavelength filtering coating membrane is formed by alternately stacking the high refractive index layers and the low refractive index layers. The high refractive index layer means that the membrane layer has a refractive index higher than that of the previous membrane layer, the low refractive index layer means that the membrane layer has a refractive index lower than that of the previous membrane layer, and the first membrane layer is defined as a high refractive index layer or a low refractive index layer based on the second membrane layer as a comparing standard. For example, if the refractive index of the first membrane layer is larger than that of the second membrane layer, the first membrane layer is a high refractive index layer; and if the refractive index of the first membrane layer is smaller than that of the second membrane layer, the first membrane layer is a low refractive index layer.

The total thickness of the long-wavelength filtering coating membrane can be the sum of the thicknesses of the long-wavelength filtering coating membranes on the object-side surface and the image-side surface of each of the optical lens elements. Because the long-wavelength filtering coating membrane can be disposed on the object-side surface and the image-side surface of different optical lens elements, the total number of layers and the total thickness of the long-wavelength filtering coating membrane should be calculated for all of the membrane layers that substantially have the filtering effects of the long-wavelength light of all of the optical lens elements. The material of the membrane layer can include (Wavelength=587.6 nm) MgF₂(1.3777), SiO₂(1.4585), ThF₄(1.5125), SiO (1.55), CeF₃(1.63), Al₂O₃(1.7682), Y₂O₃(1.79), HfO₂(1.8935), ZnO (1.9269), Sc₂O₃(1.9872), AlN (2.0294), Si₃N₄(2.0381), Ta₂O₅(2.1306), ZrO₂(2.1588), ZnS (2.2719), Nb₂O₅(2.3403), TiO₂(2.6142) and TiN (3.1307).

Furthermore, if the curvature of the coated lens element has a greater change, the atomic layer deposition (ALD) should be used so as to achieve the best uniformity of the membrane, so that the integral efficacy of the long-wavelength filtering coating membrane can be ensured.

In the arranging position of the anti-reflective coating membrane of the present disclosure, the anti-reflective coating membrane can be disposed on the object-side surface or the image-side surface of the optical lens element. Therefore, an excellent anti-reflection effect can be obtained, the serious reflection problems in the peripheral region of the optical lens element caused by the large angle of light incident on the surface thereof can be reduced, and thus the light transmittance of the optical lens assembly can be improved effectively so as to achieve the best anti-reflection effect.

In the membrane composition of the anti-reflective coating membrane of the present disclosure, the anti-reflective coating membrane can include at least one membrane layer which can be formed by alternately stacking high refractive index layers and low refractive index layers, formed by subwavelength structures, formed by the combination of the high refractive index layers and the subwavelength structures, formed by the combination of the low refractive index layers and the subwavelength structures, or formed by the combination of the high refractive index layers, the low refractive index layers and the subwavelength structures. The anti-reflective coating membrane can include a long-wavelength filtering coating membrane on the inside (adjacent to the substrate). The anti-reflective coating membrane can include the subwavelength structures disposed on the outer side (adjacent to the air), and the material of the subwavelength structures can be a metal oxide such as aluminum oxide (Al₂O₃).

The best coating surface shape of the optical lens element of the present disclosure is determined based on the horizontal displacement of the optical lens element at the position of the maximum effective diameter, the central thickness of the optical lens element and the radius of curvature at the center of the optical lens element so as to divide 0 F to 1.0 F (1.0 field of view) into 50 equal parts to get 51 fields of view namely 0 F, 0.02 F, 0.04 F, 0.06 F, 0.08 F, 0.10 F, 0.12 F, 0.14 F, 0.16 F, 0.18 F, 0.20 F, 0.22 F, 0.24 F, 0.26 F, 0.28 F, 0.30 F, 0.32 F, 0.34 F, 0.36 F, 0.38 F, 0.40 F, 0.42 F, 0.44 F, 0.46 F, 0.48 F, 0.50 F, 0.52 F, 0.54 F, 0.56 F, 0.58 F, 0.60 F, 0.62 F, 0.64 F, 0.66 F, 0.68 F, 0.70 F, 0.72 F, 0.74 F, 0.76 F, 0.78 F, 0.80 F, 0.82 F, 0.84 F, 0.86 F, 0.88 F, 0.90 F, 0.92 F, 0.94 F, 0.96 F, 0.98 F and 1.0 F, and the highest point of the light passing through all of the 51 fields of view is the maximum of the effective diameter. The direction of the horizontal displacement means the direction that the optical axis passes through the optical lens element. The horizontal displacement at the position of the maximum effective diameter is a horizontal displacement from the center of the optical lens element to the position of the maximum effective diameter. The radius of curvature of the optical lens element is calculated based on the target point of the optical lens element and two points that are 1E-10 mm upper and lower away from the target point in the direction perpendicular to the optical axis.

The transmittance of the optical lens assembly of the present disclosure means the transmittance at the incident angle of 0 degrees, and the transmittance and the average transmittance are calculated based on 5 nm as an interval. The wavelength at 50% transmittance of the optical lens assembly means the wavelength at 50% transmittance at which the transmittance decreases along with the increase of the wavelength.

In the compensating technology of the optical lens element of the present disclosure, when the optical lens element is made of the plastic material, the surface shape change error thereof will be too large due to high temperature, especially when the thickness of the optical lens element is too small. When the number of layers is larger, the precision of the surface shape is affected by the temperature more obviously. Thus, by the lens compensating technology, the problem of temperature effect while coating on the plastic surface can be effectively solved, so that it is favorable for maintaining the integrity of the coating on the optical lens element and the high precision of the plastic lens element, and it is the key technology for achieving the high quality of the optical lens assembly. The lens compensating technology can be the moldflow analysis method, the curve fitting method or the wavefront error method, but the present disclosure is not limited thereto. The moldflow analysis method is to find the three-dimensional contour nodes of the lens surface shrinking in the Z-axis through mold flow analysis, and then the three-dimensional contour nodes are converted into an aspherical curve so as to compare with the original curve to find the difference there between. At the same time, the material shrinkage rate and the surface deformation trend are considered so as to calculate and obtain the compensation value. The curve fitting method is to measure the surface contour error of the element, then the curve fitting is performed based on a function, and then an optimization algorithm method is used to approximate the fitted curve to the measurement point so as to obtain the compensation value. The function can be exponential or polynomial, and the algorithm method can be Gauss Newton method, the simplex algorithm method, the steepest descent method, etc. The wavefront error method is to measure the wavefront error (imaging error) data by the interferometer, the wavefront error generated by the manufacturing and the assembly is comprehensively analyzed by the original design value of the wavefront error and then is optimized by an optical software so as to obtain the compensation value.

The cover glass of the optical lens assembly of the present disclosure can be disposed on the object side of the image sensor, and at least one or both of the object-side surface and the image-side surface of the cover glass can include the anti-reflective coating membrane. There can be or without an air layer between the cover glass and the image sensor. When the optical lens assembly of the present disclosure is designed as an optical system with the air layer between the cover glass and the image sensor, the anti-reflective coating membrane can be manufactured on at least one or both of the object-side surface and the image-side surface of the cover glass. When the optical lens assembly of the present disclosure is designed as an optical system without the air layer between the cover glass and the image sensor, the anti-reflective coating membrane can be manufactured on the object-side surface of the cover glass. At least one or both of the object-side surface and the image-side surface of the cover glass can include the long-wavelength absorbing material. By the arrangement that the long-wavelength absorbing material is mixed with the polymer with high molecular weight, the polymer with high molecular weight can be disposed on the surface of the cover glass. Further, when the optical lens assembly of the present disclosure is designed as an optical system with the air layer between the cover glass and the image sensor, at least one or both of the object-side surface and the image-side surface of the cover glass can be designed to include the long-wavelength absorbing material membrane layer. When the optical lens assembly of the present disclosure is designed as an optical system without the air layer between the cover glass and the image sensor, the object-side surface of the cover glass can be designed to include the long-wavelength absorbing material membrane layer.

The micro lens of the optical lens assembly of the present disclosure can be disposed on the object side of the image sensor, and the object-side surface and the image-side surface of the micro lens can include the long-wavelength absorbing material. By the long-wavelength absorbing material is mixed with the polymer with high molecular weight, the polymer with high molecular weight can be disposed on the surface of the micro lens, the polymer with high molecular weight can be disposed between the micro lens and the color filter as a connecting layer, or the long-wavelength absorbing material can be mixed in the color filter. Further, the long-wavelength absorbing material can be disposed in the red filter, the green filter and the blue filter.

In the application of the optical lens assembly of the present disclosure, the optical element of the optical lens assembly can be disposed on a surface of the image sensor. By the arrangement that the long-wavelength filtering coating membrane is arranged on the surface of the optical lens element, it is favorable for reducing the angle at which the chief ray on the field of view at the maximum image height is incident on the image sensor in the optical lens assembly, so that the back focus length and total length can be reduced. In order to make the refractive index of the optical element and the refractive index of the surface of the image sensor close to each other or the same, a polymer with high molecular weight can be disposed between the optical element and the image sensor. Thus, the light can pass directly through the interface between the cover glass and the image sensor without refraction, and the angle of incidence becoming larger caused by the re-refraction can be avoided.

Each of the aforementioned features of the optical lens assembly of the present disclosure can be utilized in numerous combinations, so as to achieve the corresponding functionality.
