Abstract
The utility model discloses a prevent sapphire apron coating film of blue light injury, characterized by arranges the si3N4 layer that thickness is 32 nanometers from inside to outside in proper order on the sapphire base plate, thickness is the siO2 layer of 41.6 nanometers, thickness is the si3N4 layer of 57.3 nanometers, thickness is the siO2 layer of 42.2 nanometers, thickness is the si3N4 layer of 47.1 nanometers, thickness is the siO2 layer of 51.7 nanometers, thickness is the si3N4 layer of 40.7 nanometers, thickness is the siO2 layer of 17.3 nanometers, thickness is the si3N4 layer of 114.9 nanometers, thickness is the siO2 layer of 107.5 nanometers. The selective transmissivity that by a wide margin reduces the blue light of utility model ability, and other chromatic light high efficiencies are passed through, reduce the colour difference, fully guarantee beautiful in colors.
Description
Technical field
The utility model relates to optical coating field, is exactly the transmitance being reduced blue light by plated film specific aim specifically, thus plays the object of protection eyes.
Background technology
Current masses are more deep to the understanding of uv damage eyes, and when going out, especially sunlight is than when stronger, and a lot of people can select to wear armour to prevent ultraviolet to the injury of human eye.But a lot of people is not enough to the injury understanding of the shortwave blue light in visible ray to eyes, and according to scientific validation, high energy shortwave blue light is to the extent of injury of human eye not second to ultraviolet power, and just a lot of people exists the knowledge blind area understood blue light.In fact, in visible ray, blue light is a kind of high energy short wavelength light having energy, blue light can just penetrate the crystalline lens of glasses easily and reach retina place, eyes entirety is caused to a kind of infringement of spectrochemical property, the oxidizing process of eyes macular region can be accelerated rapidly and injury is greatly produced to eyes, and irreversible.High energy shortwave blue light, to eye ground and lenticular destruction, is called " blue light injury " phenomenon.
High energy shortwave blue light is ubiquitous in our life, has the shadow of blue light as LED, computer monitor, mobile phone, digital product, LCDs, super bath etc.Blue light injury eyes, skin, impact sleep, affects teenagers healthy growth, increases the ill probability of eyes.
The description of prior art
Prior art is exactly mostly: regardless of blue light or other colored light, no matter be harmful harmless, transmitance all significantly reduces, and is in fact just equivalent to add a curtain, reduces display brightness, does not have the object of shooting the arrow at the target.
The description of new technology
The utility model discloses the sapphire cover plate plated film of a kind of anti-blue light injury, it is characterized in that on sapphire substrate, be arranged in order the Si that thickness is 32 nanometers from inside to outside

The utility model on the basis of existing technology, has selected precision manufactureing technique, effectively can control the blue light transmitance of 400 ~ 500nm wavelength, and ensures that the later light penetration of 500nm wavelength is on average more than 99%.
The thickness that above-mentioned each material is corresponding, its permission changes in margin tolerance, and the scope of its change belongs to the scope of this patent protection, is identity relation.The tolerance of usual thickness is at 10 ran.
Summary of the invention
The utility model is by plated film on sapphire substrate, and specific aim reduces the transmitance of blue light, and all the other coloured light still keep high permeability, so both reach protection eyes, reduces again the object of color distortion as far as possible.
