Embodiment 1

[0054] In this embodiment, the anti-reflection film 40 only has the base bonding layer 41 and the microstructure layer 42 , and the base bonding layer 41 and the microstructure layer 42 form a combined layer and are disposed on the plane section 31 and the slope section 32 . In this embodiment, the barrel section 10 , the image end 20 and the object end 30 are made of opaque plastic. In this embodiment, the base bonding layer 41 is SIO, and the film thickness of the base bonding layer 41 is 5nm, the microstructure layer 42 is made of a fullerene material having a nano-hollow sphere microstructure, and the microstructure layer 42 The thickness is 500nm. Such as image 3 As shown, the reflectance of the anti-reflection film 40 to light with a wavelength of 380nm to 780nm is about 0.2%.

Embodiment 2

[0056] The difference from the first embodiment is that the specific structure of the antireflection film 40 is different.

[0057] In this embodiment, the anti-reflection film 40 has a base bonding layer 41, a microstructure layer 42 and a low-refractive film layer 43, and the base bonding layer 41 and the microstructure layer 42 form a combined layer and are arranged on the plane section 31 and the slope section 32 Above, the low-refractive film layer 43 is disposed on the last combined layer. In this embodiment, the base bonding layer 41 is SIO, and the film thickness of the base bonding layer 41 is 5nm, the microstructure layer 42 is made of a fullerene material having a nano-hollow sphere microstructure, and the microstructure layer 42 The thickness is 500nm. Low refractive film layer 43 is SiO 2 , and the thickness of the low-refractive film layer 43 is 90 nm. Such as Figure 5 As shown, the reflection rate of the anti-reflection film 40 to light with a wavelength of...

Abstract

The invention provides a low-reflection plastic lens barrel, a manufacturing method thereof, an imaging lens group and a camera device. The low-reflection plastic lens barrel is light-proof and comprises a barrel body section, a lens body section and a lens body section, the image end part is arranged at one end of the cylinder body section; the object end part is arranged at the other end of thecylinder body section; the surface of one side, far away from the barrel section, of the object end part comprises a plane section and a slope section; wherein the inclined plane section is close to the central axis of the cylinder section relative to the plane section, the inclined plane section inclines from the plane section to the direction close to the central axis and extends towards the image end part, the plane section and the inclined plane section are plated with antireflection films, each antireflection film comprises a substrate bonding layer and a microstructure layer, and the microstructure layers are far away from the object end part relative to the substrate bonding layers. According to the invention, the problem of poor light absorption effect of the plastic lens cone in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of imaging of optical equipment, in particular to a low-reflection plastic lens barrel, a manufacturing method thereof, an imaging lens group and an imaging device. Background technique [0002] The optical lens is used to image the subject to the imaging surface, such as the optical lens of the mobile phone imaging on the sensor, such as the telescope that can observe the imaging with the naked eye. The lens determines the quality of the imaging performance, so the lens performance has become an important consideration in the design of cameras and other equipment, and in recent years, portable electronic devices such as mobile phones have higher and higher requirements on the lens. [0003] Optical lenses usually include optical elements such as plastic lens barrels, optical lens groups, shading sheets, and spacer rings. The optical lens groups are arranged in plastic lens barrels. The optical lens groups i...
