Both surfaces of our standard substrates are laser grade polished. These substrates are ideal base for plate beamsplitters, optical windows, partially reflective mirrors, etc.
Laser components require highly polished substrates as well as high performance coatings. Scattering, damage by laser light can occur if the substrate is made of inferior material or is inadequately polished. For UV and very high power applications we recommend using UVFS substrates. BK7 substrates are an economical solution for laser components used in many laboratory applications as well as in many devices and instruments.
We provide various dielectric and metallic coatings.
