Laser protective glasses are special glasses that can prevent or reduce laser damage to human eyes. Laser protective goggles are highly efficient and safe goggles, which are suitable for a variety of lasers and laser pointers. This series of optical safety glasses is comfortable, beautiful, safe and reliable to wear. Its optical safety performance fully meets GJB1762-93, and the laser safety glasses have reflective and absorptive types, which can protect laser and strong light of specific wavelengths in all directions. When the incident laser energy exceeds a certain value, the anti-laser radiation protective glasses micro-explosion protective glasses: the outer surface of the lens is coated with a specific high-transparency chemical film. The explosion of chemicals turns black, making the lens completely opaque, thereby protecting the eyes from Laser pointer damage. The protective goggles are more suitable for high-power continuous lasers. Moreover, it is also sensitive to light intensity, and the realization of laser protection using the principle of nonlinear optics has become a research hotspot in many countries. Non-linear laser protective glasses made of this material are not only sensitive to wavelength. It can realize the unification and consideration of the two indicators of high optical density of strong light and high transparency of weak light at the same laser wavelength.
The protection performance is related to the intensity of the beam, not to the wavelength. Use the Fourier transform principle to attenuate the laser intensity and prevent laser radiation from mirror image aberration. Laser protective glasses: This kind of protective glasses is usually filled with water and alcohol between two layers of glass or cellophane. The laser is prevented from damaging the retina, and the protective wavelength can cover the entire spectrum without affecting the user's visual sensitivity.
