Abstract
The utility model discloses a kind of mobile phone white glass optical filter, including substrate, the infrared cut coating being arranged on the left of substrate and the antireflective film being arranged on the right side of substrate, the substrate are made up of white glass, and the antireflective film is folded into by 9 layers of anti-reflection film layer；The optical thickness of the anti-reflection film from right to left is followed successively by：203.57~223.57nm, 16.97~20.97nm, 43.19~53.19nm, 28.52~34.52nm, 15.9~19.9nm, 72.05~82.05nm, 14.42~18.42nm, 25.89~31.89nm and 96.85~106.85nm.The utility model has accurately anti-reflection effect to the light of 400~700nm wave-length coverages, and anti-reflection effect is good, anti-reflection stable performance.
Description
Technical field
It the utility model is related to a kind of optical filter, and in particular to a kind of mobile phone white glass optical filter.
Background technology
It is known that reflex can occur on the interface of two media for light, when light vertical irradiation to uncoated glass
During surface, its reflected light accounts for the 8% of incident light.In the application of many optical elements, the reflection on its surface not only influences
The thang-kng energy of optical element, and these reflected lights can also form veiling glare in instrument, so as to influence optical instrument into
As quality.In order to solve these problems, generally anti-reflection film is plated on the surface of optical element, in order to reduce element table
The reflected light in face, increase the transit dose of light.
Camera lens on camera often has specific requirement to the wavelength of light of anti-reflection and filtering, and wavelength is 400~700nm
When light light transmission capacity is big, reflected light is few, image is softer, clear, true.Existing white glass optical filter anti-reflection passage is not smart
It is accurate so that white glass optical filter can not coordinate machine to reach optimal photographic effect.
Utility model content
The utility model provides a kind of mobile phone white glass optical filter, by setting infrared section in the left side of white glass substrate
Only film, sets antireflective film on the right side of white glass substrate, and antireflective film is folded into by 9 layers of anti-reflection film layer so that the utility model pair
The light of 400~700nm wave-length coverages has accurately anti-reflection effect, and anti-reflection effect is strong.
In order to solve the above technical problems, the utility model adopts the following technical scheme that：
A kind of mobile phone white glass optical filter, including substrate, the infrared cut coating that is arranged on the left of substrate and it is arranged on base
Antireflective film on the right side of plate, the substrate are made up of white glass, and the antireflective film is folded into by 9 layers of anti-reflection film layer, multilayer anti-reflection
Film is used to construct anti-reflection passage of the wave-length coverage for 400~700nm, and strengthens anti-reflection effect.
Further, for the utility model is better achieved, the thickness of the anti-reflection film from right to left is followed successively by：
203.57~223.57nm, 16.97~20.97nm, 43.19~53.19nm, 28.52~34.52nm, 15.9~19.9nm,
72.05~82.05nm, 14.42~18.42nm, 25.89~31.89nm and 96.85~106.85nm；The film energy of different-thickness
The infrared light of anti-reflection different wave length, the film of 9 layers of different-thickness form the anti-reflection passage that a wave-length coverage is 400~700nm；This
Gap is big between the adjacent antireflective film of utility model, and the maximum two membranes of thickness are separately positioned on first layer and last layer, make
Bigger, the better control of relative thickness between adjacent two layers film is obtained, is also beneficial to strengthen anti-reflection effect, enhancing anti-reflection passage
Stability.
Further, for the utility model is better achieved, the anti-reflection film is magnesium fluoride class antireflective film or titanium dioxide
Titanium class.
The beneficial effects of the utility model：
The utility model has good light anti-reflection effect, and the light anti-reflection passage at 400~700nm wavelength consolidates, temperature
Floaing, it is small to influence, and coordinates the image at cameras bat to become apparent from, truly.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is 9 layers of anti-reflection film 5 structural representation of the present utility model.
Symbol description in figure：Substrate 1, infrared cut coating 2, antireflective film 3, anti-reflection film 4.
Embodiment
The utility model specific embodiment is described further referring to the drawings.
A kind of mobile phone white glass optical filter, including substrate 1, be arranged on the infrared cut coating 2 in the left side of substrate 1 and be arranged on
The antireflective film 3 on the right side of substrate 1, the substrate 1 are made up of white glass, and the antireflective film 3 is made up of 9 layers of stacking of anti-reflection film 4.
The thickness of the anti-reflection film 4 from right to left is followed successively by：203.57~223.57nm, 16.97~20.97nm,
43.19~53.19nm, 28.52~34.52nm, 15.9~19.9nm, 72.05~82.05nm, 14.42~18.42nm,
25.89~31.89nm and 96.85~106.85nm.
The anti-reflection film 4 is that any one of magnesium fluoride class antireflective film or titanium dioxide class antireflective film are made.
The scope of protection of the utility model is not limited merely to above-described embodiment, all skills belonged under the utility model thinking
Art scheme belongs to the scope of protection of the utility model.It should be pointed out that for those skilled in the art,
Some improvements and modifications under the premise of the utility model principle are not departed from, these improvements and modifications also should be regarded as of the present utility model
Protection domain.
