We hear a few words of Laser safety glasses every day, but we don't havemuch of a group to really see and understand. Yesterday, laser protection window operators to share with you what exactly is the laser protective mirror,and then we look at the specific meaning. Expect to bring certain support.
It is easy for laser of a kind of special prevention or reduction of the laser mirror eye slander. Laser is a kind of efficient insurance goggles, suitable for various laser, laser pen, a series of optical mirror wearing comfortable, goodlooking, insurance insurance firm. The optical properties of GJB176293 laser completely meet the insurance, insurance type, albedo mirror has the attraction type, allround protection of a certain band of laser and glare.Suitable for various laser facilities. The visible light transmittance reached above 70%. The optical density was 5 (OD+5, OD+6).
First, suitable to wear laser protective mirror at
A practical: laser operators, computer operator, driver, welder, welding arcreactor and low temperature furnace operation personnel, medical personnel to operate the X- light or light industrial perspective; protection applied to ultraviolet laser, excimer laser, Nd: glass laser, superconductor laser, CO laser,Nd: YAG, ruby laser, CO2 laser, laser and other lasers of GaAs
Two, how to choose suitable laser protective mirror
There are many varieties of laser protective mirror, the opposite of the information, the principle of different, the use of the opposite.
Therefore, to provide the laser invalid protection, must according to specific application to continue to proper choice of laser protective glasses. Choose the door mirror, according to the maximum input power (or energy), the laser beam diameter, laser pulse time and other parameters to determine the maximum radiation input or the maximum amount of radiation. Then, according to the corresponding time span and the maximum allowable amount of radiation shine(shine eye limit) to determine the mirror the minimum optical density value, and then selects suitable protective glasses. Specific conditions of choice areimportant:
1, the maximum amount of radiation Hmax (J/m2) or maximum radiation degreeEmax (W/m2).
2, a certain protection span.
In 3, the optical density value of Dmin to the corresponding protection span.
4, the non symmetry of the protective lens, asymmetric, the incident light effect, etc..
5, the power of anti laser radiation.
6, visible light transmittance.
7, structure and shape.
Above is the work of the Laser safety glasses for everyone to bring, forwhat is the meaning of the laser protection mirror share. We expect everyone to see after the support, then we want to know more about the laser protection of common sense and meaning. Please pay more attention to us.
