Why Choose Our Laser Safety Glasses
LASERPAIR CO., LIMITED There are many types of laser protective glasses, with
different principles and different usage occasions. Therefore, in order to provide effective
protection against lasers, it is necessary to make a proper choice of laser protective glasses
2/3
according to specific applications.
When using protective goggles, the maximum input radiation intensity or maximum
radiation dose of the laser should be determined according to the maximum input power
(or energy), beam diameter, pulse duration and other parameters of the laser used. Then,
determine the minimum optical density value required by the mirror surface according to
the maximum allowable radiation amount (eye exposure limit) of the corresponding span
and illumination time, and select suitable protective glasses accordingly.
The specific conditions for the choice are:
1. The maximum radiation amount Hmax (J/m2) or the maximum radiation intensity
Emax (W/m2);
2. A certain protection span;
3. The required minimum optical density value Dmin in the corresponding protection
span
4. The asymmetry, asymmetry of the protective lens, the viewpoint effect of incident
light, etc.;
5. Anti-laser radiation power;
6. Visible light transmittance;
7. Structure and shape.
American laser insurance specification ANSI Z136.1ANSI Z136.1 specification: Continue
to weigh the optical density (OD, Optical Density). Theoretical relationship between
optical density OD and transmittance T: D=-log10 T. European laser insurance standard
EN207/EN208EN207/EN208 standard: consider the optical density OD, and also need
to consider the damage threshold. According to the American laser insurance
specification ANSI Z136.1 and the European laser insurance specificat
