Sid SD-4 laser protective eyewear Sid safety glasses are a series of light from the light-absorbing polymer materials and synthetic materials, an efficient safety goggles. Its shieldTM optical security performance to fully meet European standards EN207A1: 2002. Sid Company series optical safety glasses to wear comfortable, beautiful, safe and reliable. Sid Company series optical safety glasses absorption principle: light absorption principle. The angle of incidence of the light source is not selective, specific bands can be full protection of the laser and light.
