DETAILED DESCRIPTION

The present disclosure provides an imaging lens assembly. The imaging lens assembly includes a first optical element and a low-reflection layer. The first optical element has a central opening, and includes a first surface, a second surface and a first outer diameter surface. The first surface faces towards one side of an object side and an image side of the imaging lens assembly and surrounds the central opening. The second surface faces towards the other side of the object side and the image side of the imaging lens assembly and surrounds the central opening. The first outer diameter surface is connected to the first surface and the second surface. The low-reflection layer is located on at least one of the first surface and the second surface, and includes a carbon black layer, a nano-microstructure and a coating layer. An appearance of the carbon black layer is black, and the carbon black layer is directly contacted with and connected to the at least one of the first surface and the second surface. The nano-microstructure is a porous structure form, and the nano-microstructure is directly contacted with and connected to the carbon black layer. The nano-microstructure is farther from the first optical element than the carbon black layer from the first optical element. The coating layer is directly contacted with and connected to the nano-microstructure, and the coating layer is farther from the first optical element than the nano-microstructure from the first optical element. When a reflectivity of the low-reflection layer at a wavelength of 400 nm is R40, a reflectivity of the low-reflection layer at a wavelength of 800 nm is R80, and a reflectivity of the low-reflection layer at a wavelength of 1000 nm is R100, the following conditions are satisfied: R40≤0.40%; R80≤0.40%; and R100≤0.40%.

Furthermore, the first optical element can be a plastic product such as a lens barrel, a spacer, a retainer, a light blocking element or a light blocking sheet, and so on, but is not limited thereto. Further, a gap does not exist between the first surface and a surface of the first optical element and between the second surface and the surface of the first optical element.

The low-reflection layer can be in a full-circle form or a layered structure, wherein the nano-microstructure of the low-reflection layer can be for absorbing the non-imaging stray light. Moreover, the carbon black layer is disposed on the at least one of the first surface and the second surface of the first optical element via a spray process, and the nano-microstructure is formed by the carbon black layer treated via a special treatment. Hence, a composition of the nano-microstructure is the same as a composition of the carbon black layer. In particular, the special treatment can be a surface roughening process of the carbon black layer, and then the nuclear reaction is performed on a surface of the carbon black layer with a proper material, such as the physical vapor deposition, the chemical vapor deposition, the vacuum evaporation, the sputtering, the ion plating, and so on. A surface structure with a nano-crystallization is formed via the crystallization process, and the surface structure of the nano-crystallization is the nano-microstructure. After forming the nano-microstructure, the coating layer is disposed on an external of the nano-microstructure to protect a nanostructure thereof. Therefore, it is favorable for strengthening the durability and the structural stability of the low-reflection layer. The carbon black layer is directly contacted with and connected to the nano-microstructure, and the nano-microstructure is directly contacted with and connected to the coating layer. Also, the gap does not exist between the carbon black layer and the nano-microstructure and between the nano-microstructure and the coating layer.

In detail, a reflection intensity of the stray light is weakened by the extremely low reflectivity of the low-reflection layer to further enhance the image quality. Further, different from techniques of prior art such as the inking process, the blasting process and the coating process, the insufficiency of the structural support of the low-reflection layer is improved by the low-reflection layer. The coating layer can be a single-layer film. Although the better anti-reflection effect can be obtained via a multi-layer film of prior art, a process of prior art is more complicated and high-cost, and the aforementioned problem can be improved by the present disclosure. By a choice of a material of the coating layer, surface characteristics of the low-reflection layer can be further changed, for example, the anti-oxidation ability can be enhanced; the light intensity of the light reflecting from a surface can be decreased, and so on.

When a reflectivity of the low-reflection layer at a wavelength of 380 nm is R38, the following condition can be satisfied: R38≤0.40%. Therefore, it is favorable for enhancing the image quality. Further, the following condition can be satisfied: R38≤0.30%. Further, the following condition can be satisfied: R38≤0.20%.

When a grain pitch of the nano-microstructure is GP, the following condition can be satisfied: 5 nm≤GP≤200 nm. In particular, the grain pitch of the nano-microstructure is a minimum distance between peaks of each of grains. Therefore, it is favorable for ensuring the grain pitch smaller than the wavelength of the visible light. Further, the following condition can be satisfied: 10 nm≤GP≤130 nm. Further, the following condition can be satisfied: 22 nm≤GP≤95 nm.

When a reflectivity of the low-reflection layer at a wavelength of 680 nm is R68, the following condition can be satisfied: R68≤0.40%. Therefore, it is favorable for decreasing the problem of the reddish coating and enhancing the image quality. Further, the following condition can be satisfied: R68≤0.30%. Further, the following condition can be satisfied: R68≤0.20%.

When the reflectivity of the low-reflection layer at the wavelength of 400 nm is R40, the reflectivity of the low-reflection layer at the wavelength of 800 nm is R80, and the reflectivity of the low-reflection layer at the wavelength of 1000 nm is R100, the following conditions can be satisfied: R40≤0.30%; R80≤0.30%; and R100≤0.30%. Further, the following conditions can be satisfied: R40≤0.20%; R80≤0.20%; and R100≤0.20%.

The imaging lens assembly can further include a second optical element. The second optical element includes a second outer diameter surface, and a maximum diameter of the second outer diameter surface is smaller than a diameter of the first outer diameter surface of the first optical element, the second optical element and the first optical element are assembled to each other along a direction parallel to an optical axis, and the first optical element faces towards the second optical element. Therefore, a surface of the first optical element can have a larger area of the low-reflection layer to eliminate the stray light from the external of the imaging lens assembly. Also, it is favorable for decreasing the background noise of the imaging to enhance the imaging sharpness.

The coating layer can be made of a silicon oxide (SiO₂). When the coating layer is made of the silicon oxide, it is favorable for enhancing the anti-oxidation ability of the low-reflection layer, and a refractive index of the silicon oxide is 1.46. Therefore, it is favorable for preventing the oxidation of the nano-microstructure and the oxidation of the carbon black layer to promote the durability of the low-reflection layer.

The coating layer can be made of a metal oxide. Therefore, a surface hardness and an abrasion resistance of the low-reflection layer can be further enhanced.

The coating layer can be made of a titanic oxide (TiO₂). The titanic oxide is a high refractivity material to lower the light intensity of the light reflecting from the surface of the low-reflection layer, and a refractive index of the titanic oxide is 2.24-2.37. Moreover, the coating layer can be made of an aluminum oxide (Al₂O₃), a metal nitride, a metal fluoride, and so on, and a refractive index of the aluminum oxide is 1.56. By a characteristic of the refractive index of different materials of the coating layer, a graded index can be obtained between the low-reflection layer and an air to lower the light intensity of the light reflecting from the surface of the low-reflection layer.

Each of the aforementioned features of the imaging lens assembly can be utilized in various combinations for achieving the corresponding effects.
