We can provide special optical polishing service for optics or wedge substrate that achieve surface roughness of <0.2nm (Ra). These low scattering substrates are in high demand for high power laser and X-ray applications.

◦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).

▶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.

The definition of surface roughness is defined according to the JIS B0601 standard. The most commonly used parameter is Ra. The Ra is usually shown on specifications by Å Angstrom unit (0.1nm).
The definition of Ra value is the calculation of the measured value and the average value; the absolute value is the subtraction of the measured value to the average value. Similar to Root-Mean-Square value (RMS) but with a little bit smaller number.
