Laser window

Windows are used to isolate different physical environments while allowing light to pass. When selecting windows you should consider materials, transmission, scattering, wavefront distortion, parallelism and resistance to certain environments.

Lasertec manufacturers high precision laser windows for applications starting at 193 nm. Windows can be manufactured from a variety of materials including sapphire, optical glasses, fused silica,  CaF2, MgF2, and Cleartran. Our controlled manufacturing process provide low transmitted wavefront distortion, high parallelism, low scatter, high laser damage resistance and exceptional environmental durability

Application:

Medical Laser system
Laser cutting
Laser welding
Industrial Q-Switch Laser system
