Embodiment Construction

[0078] A method for designing a color-controllable high-energy visible light filter, comprising the following steps:

[0079] Step 1: Select a filter, said filter contains a dye that absorbs short-wave visible light, and the transmittance T of the filter is expressed as a function of various parameters of the optical device.

[0080] The transmittance T(λ) of the filter at each wavelength is expressed as the following function:

[0081]

[0082] Among them, N is the total number of effective light-absorbing components i, l is the effective total thickness of all medium layers where the effective light-absorbing components i are distributed, ε i is the molar absorptivity of effective light-absorbing component i, c i is the average concentration of active ingredient i in all the medium layers where it is distributed, λ is the wavelength of visible light; M is the total number of effective reflective interfaces, f j is the reflectance of the effective reflective interface j....

Abstract

A design method of a color-controllable high-energy visible light filter comprises the following steps: selecting a filter, wherein the filter contains dye for absorbing short-wave visible light, andthe transmissivity T of the filter is expressed as a function of each parameter of an optical device; Selecting a light source, selecting a color group consisting of one color or a plurality of colors, and expressing each color sensing parameter of the color or the color group required to be optimized as a function comprising a light source D and filter transmissivity T; In a 1976 CIE L * a * b *color sensing space, according to the chroma to be optimized, selecting an optimization vector (shown in the specification) to express the comprehensive chromatic aberration of the color or the colorgroup projected on the chromaticity plane required to be optimized as an E optimization color axis T; And performing multi-objective optimization according to the color sensing parameter required foroptimizing the transmission spectrum and the E optimization color axis and T, selecting an appropriate solution, namely, the transmissivity T of the filter, and further optimally designing each parameter of the optical device of the filter based on a function expressed by the transmissivity T.

Description

technical field [0001] The invention relates to a design method of a color-controllable high-energy visible light filter. Background technique [0002] Recent studies have shown that high energy visible light (high energy visible light), that is, visible light with a shorter wavelength, usually around 380nm to 480nm, has a harmful effect on the human eye, especially the retina. One of the more well-known harmful effects is age related macular degeneration induced and accelerated by high-energy visible light. The human eye can be divided into two parts: the retina composed of photoreceptor cells (rod cells and cone cells), and the refractive system composed of cornea, aqueous humor, lens and vitreous body. When the eye's photoreceptor cells absorb and sense light, the visual pigment molecules that line the outer disc lose their color (bleach). They need to go through a metabolic process before they can absorb and perceive light again. This metabolic process is called the v...
