Abstract
The invention discloses a coating material capable of reducing reflectivity of an optical lens. The coating material comprises a substrate, wherein a trititanium pentoxide film layer, a silicon dioxide film layer, a trititanium pentoxide film layer, a silicon dioxide film layer, a trititanium pentoxide film layer and a silicon dioxide film layer are arranged on the substrate sequentially from inside to outside. The material of the substrate is APEL with a refractive index of 1.54. The refractive index of the trititanium pentoxide film layer is 2.137. The refractive index of the silicon dioxide film layer is 1.46. The oxygenation capacity of the trititanium pentoxide film layer is 1.2E-2pa, the evaporation rate is 2.5A/S, and the evaporation current is 260A. The oxygenation capacity of the silicon dioxide film layer is 0, the evaporation rate is 6A/S, and the evaporation current is 85A. The coating material disclosed by the invention changes the original 5 layers into 6 layers, the wavelength wideband is improved from 420-680nm to 400-700nm, the reflectivity is improved from R<0.7% to R<0.5%, and therefore, a higher definition is obtained.
Description
Technical field
The present invention relates to a kind of Coating Materials reducing optical glass reflectance.
Background technology
Reflection and refraction can be produced when light is by different medium, and modern cell phones lens construction is more complicated, mirror
Sheet number is more, so the number of times of the reflection occurred after light entrance camera lens and refraction will be the most.Thus can
Cause two problems: one is that the light by camera lens has bigger loss；Two is that light occurs in camera lens
Multiple reflections will produce our described veiling glare and ghost with refraction；And coating technique can very effective change
These problems kind.
Plated film is transparent membrane the thinnest on camera lens plated surface.Purpose is desirable to reduce the reflection of light, increases
Adding light transmittance, uvioresistant also lowers credit light, ghost；The plated film of different colours, also makes imaged color put down
The difference of weighing apparatus.Additionally, plated film still can postpone, eyeglass is aging, the time of variable color.
The shooting photo of high-resolution, is present mobile phone use consumer demand, but existing mobile lens
Coating designs can only meet: carries a width of 420nm～680nm, reflectance R < 0.7%.In order to reach preferably effect
Really, need plated film is designed, reduce the reflectance of camera lens as far as possible, increase bandwidth.
Summary of the invention
The technical problem to be solved in the present invention is the defect overcoming prior art, it is provided that one can reduce optical frames
The Coating Materials of sheet reflectance, it can reduce the reflectance of camera lens, increase bandwidth.
In order to solve above-mentioned technical problem, the invention provides following technical scheme:
A kind of Coating Materials reducing optical glass reflectance of the present invention, it includes substrate, on described substrate
It is disposed with five oxidation three titanium film layers, silica coating, five oxidation three titanium film layers, dioxies from inside to outside
Change silicon film, five oxidation three titanium film layers, silica coatings.
Further, the material of described substrate is APEL, and its refractive index is 1.54.
Further, the refractive index of described five oxidation three titanium film layers is 2.137.
Further, the refractive index of described silica coating is 1.46.
Further, described five oxidation three titanium film layers oxygenation capacities be 1.2E-2pa, evaporation rate be
2.5A/S, evaporation current are 260A.
Further, the oxygenation capacity of described silica coating be 0, evaporation rate be 6A/S, evaporation current
For 85A.
The present invention is reached to provide the benefit that:
The present invention changes former 5 tunics as 6 tunics into, and wavelength broadband is brought up to 400nm-by 420nm-680nm
700nm, reflectance is risen to R < 0.5% by R < 0.7%, obtains higher definition.
Detailed description of the invention
Hereinafter the preferred embodiments of the present invention are illustrated, it will be appreciated that described herein be preferable to carry out
Example is merely to illustrate and explains the present invention, is not intended to limit the present invention.
