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.

Details

◦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).

Name	Low Scattering Substrate CaF2 25.4mm Diameter
Weight	0.0090lbs
Standard Coatings Available	Yes
Guide	Wedged substrates have marked with an arrow indicating the direction of front surface at the thickest thickness point.
Remark	-
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.
