Embodiment Construction
[0013] The present invention is further described below.
[0014] A visible light three-wave peak coating process, including coating equipment and optical filters. During the coating process, the coating equipment uses the first film stack, the second film stack, and the third film stack to cut off the filter in different bands in the visible light region. , anti-reflection, wherein, the first film stack cuts off the central wavelength before 420nm by superimposing high and low refractive index materials, and performs anti-reflection between the central wavelength 430-1100nm; the second film stack superimposes high and low refractive index materials before the central wavelength 750nm For anti-reflection, the cut-off is performed between the central wavelength 760-1100nm; the third membrane stack cuts off the two regions of the central wavelength 500-520nm and 600-680nm, and the three bands of the central wavelength 450nm, 545nm, and 710nm are used for anti-reflection;

The invention discloses a visible light three-wave-crest membrane coating technology, which comprises film coating equipment and an optical filter, wherein the membrane coating equipment adopts a first membrane stack, a second membrane stack and a third membrane stack in a membrane coating process to carry out the cutoff and the permeability improvement of different wavebands on the optical filterin a visible light area; the first membrane stack carries out cutoff before central wavelength of 420nm through a high and low refractive index material, and caries out permeability improvement between the central wavelengths 430-1100nm; the second membrane stack carries out permeability improvement before central wavelength of 750nm through the overlapping of the high and low refractive index material, and carries out cutoff between the central wavelengths 760-1100nm; the third membrane stack carries out cutoff on two areas of which the central wavelengths are independently 500-520nm and 600-680nm and carries out permeability improvement on three wavebands of which the central wavelengths are independently 450nm, 545nm and 710nm; and a membrane coating optical filter formed after opticalfilter membrane coating is provided with three penetration areas on three positions with the central wavelengths are 480nm, 580nm and 720nm. The technology is reasonable in design and simple and cancause the optical fiber to form three visible light penetration areas in the coated membrane.
Description
technical field [0001] The invention relates to the technical field of optical filter coating, in particular to a visible light three-wave peak coating process. Background technique [0002] At present, there is no three-peak coating technology in the visible light region on the market. The three-peak technology in the visible light region can make RGB display better and clearer, and it can achieve a clearer and smoother effect when applied to the screen. In terms of current imaging technology research and development, the main focus is to enhance the clarity and fluency, so visible light three The wave crest is required for the precise development of the future direction of visible light. Contents of the invention [0003] The invention provides a visible light three-peak coating process with reasonable design and simple process, which can make the optical filter form three visible light transmission regions in the coating. [0004] In order to achieve the above object,...
