Description
Technical field
The present invention relates to three wave crest coating process of optical filter coating technical field more particularly to a kind of visible light.
Background technique
Three wave crest coating technique of visible light region is not present on the market now.Three wave crest technology of visible light region, can make
RGB is more preferably clearer to be shown, and applies on picture can achieve apparent more smooth effect, in imaging this part at present
In terms of technical research, main or reinforcement clarity fluency, so three wave crest of visible light is the accurate development of the following visible light
Direction it is required.
Summary of the invention
The present invention provide it is a kind of design rationally, the three wave crest coating process of visible light of simple process can make optical filter exist
Three visible light-transmissive regions are formed in plated film.
To achieve the goals above, the present invention use following technical scheme, a kind of three wave crest coating process of visible light, including
Filming equipment, optical filter, the filming equipment in coating process using the first membrane stack, the second membrane stack, tertiary membrane piles up can
Light-exposed region carries out the cut-off, anti-reflection of different-waveband to optical filter respectively, wherein first membrane stack passes through high low-refraction
Material superposition carries out anti-reflection to ending before central wavelength 420nm between central wavelength 430-1100nm；Described second
Membrane stack is anti-reflection to carrying out before central wavelength 750nm by the superposition of high low-index material, between central wavelength 760-1100nm
Ended；Long two regions 500-520nm, 600-680nm of the third membrane stack centering cardiac wave are ended, central wavelength
Tri- wave bands of 450nm, 545nm, 710nm carry out anti-reflection.
Preferably, first membrane stack uses TiO2And SiO2。
Preferably, second membrane stack uses TiO2And SiO2。
Preferably, the third membrane stack is that the first membrane stack is superimposed to be formed with the second membrane stack.
A kind of coated filter, the coated filter formed after the optical filter coating is in central wavelength 480nm, center
3 penetrating regions are equipped at wavelength 580nm, central wavelength 720nm.This programme penetrating region wave-length coverage is about central wavelength
Positive and negative 10nm.
This programme carries out the membrane system front and back sides plated film of three wave crests on the optical filter of buying, and the plated film for finally plating out filters
Piece reaches three wave crest of visible light, it is seen that three wave crest of light is that height occur thoroughly in visible light-transmissive region using multiple membrane stacks, passes through plating
Film device, the cut-off and transmission of high low-index material (using particularity materials such as high refractive indexes) Lai Shixian specific band,
There are 3 penetrating regions in central wavelength 480 and central wavelength 580 and central wavelength 720 or so.
The product membrane system of this programme production can be used for RGB inductor, and (rgb color mode is a kind of color mark of industry
Standard is by each to obtain to red (R), green (G), the variation of blue (B) three Color Channels and their mutual superpositions
The color of formula various kinds, RGB is the color for representing three channels of red, green, blue, this standard almost includes human eyesight institute
The all colours that can be perceived are current with most wide one of color system.Three wave crest of visible light can equally be used in us and give birth to
In display material in work, such as TV, computer, camera, video camera etc.；The eyeball of people can be allowed to have better vision body
While testing, it is more vivid brilliant and clear that capture apparatus shoots the colors such as the effect, such as photograph video come.
Therefore, the invention has the following beneficial effects: designs rationally, and simple process can make optical filter shape in plated film
At three visible light-transmissive regions.
