These PX optical flats are precision polished on both sides for high accuracy and surface quality.

OSE-OPFL

Float Glass is a glass substrate produced by the float process used in the manufacture of window glass.
These are high precision polished substrates where the material change due to the temperature variation is very small. Material: SiO2.
