T-REX Laser Safety Glasses is a highly effective explosion-proof safety goggle made of polycarbonate (PC) and a specific wavelength of light absorbing material imported from Australia. Its optical safety performance fully meets GJB1762-93 "Physical Hygiene Standard for Laser Protective Mirrors". Comfortable, beautiful, safe and reliable. Laser safety glasses adopt the principle of light absorption: they are not selective to the light source, and can safely protect all kinds of diffuse reflection light; there is no selectivity to the incident angle of the light source, and the laser and glare of a specific band can be comprehensively protected. The light response is faster. The attenuation rate is high. The surface is not afraid of wear and tear, even if it is scratched, it does not affect the safety of light. EP-3 type laser protective glasses technical parameters and applicable laser: protection band nm: 200-540 optical density: OD=4-5 applicable laser and wavelength: Ar ion laser 488-514.5nm OD=5 excimer laser He-Cd 441.6 Nm OD=5 times frequency Nd:YAG laser 532nm OD=4 ion laser 514nm OD=5 has good shielding effect on the glare white light generated in laser operation.
