Our standard substrates have a laser grade polished on both surfaces. These substrates are ideal for transmitting applications such as beamsplitters, windows, partial reflecting mirrors etc.
Laser components require highly polished substrates as well as high performance coatings. Scattering, laser damage of laser light can occur if the substrate is made of inferior material or if it is inadequately polished. For UV and very high power applications we recommend using UVFS substrates. BK7 substrates are economical solution for laser components used in many applications in laboratory as well as in many devices and instruments.
Altechna provides various dielectric and metallic coatings on optical substrates (please refer to the
Coatings section).
