◦Use a wedged substrate for a beamsplitter to prevent effects of back reflection.
◦CaF2 (calcium fluoride) and MgF2(magnesium fluoride) are mainly used in UV and IR for its high transmittance.
◦Our highly technical processing yields low surface roughness (microscopic irregularities) and precision surface accuracy (flatness of whole surface).

Guide ▶Wedged substrates have marked with an arrow indicating the direction of front surface at the thickest thickness point.
Attention ▶The low scattering substrates are uncoated; the reflectance from the surface is 2.5% to 4%.
▶If using wedge substrate for transmission application, the beam will be deviate approximately 0.5 degrees.
▶The CaF2 substrate surface can be easily scratched. Do not use contact cleaning, please use air-blow for dirt cleaning.
▶The CaF2 and the MgF2 substrates get rough under high temperature and high humidity environment. Stock them in dry optical cabinet after use.
