Optical flats are made of
WebSingle sided optical flats are used as a reference (test plate) against which the flatness of an unknown surface can be compared. Advanced Optics offers single sided optical flats made of low expansion borosilicate glass, fused silica, fused quartz and ZERODUR® up to 8 inches in diameter. Surface flatness of λ/4, λ/10 and λ/20 are available ... http://www.gagesite.com/documents/Metrology%20Toolbox/How%20to%20Measure%20Flatness%20with%20Optical%20Flats.pdf

The material used will be dependent on the application, however due to the nature of their use the materials need to be durable but can be polished to a high degree.
WebExplanation: Optical flats are generally made from fused quartz or borosilicate glass as they have the least coefficient of linear expansion. This glass is colourless and free from defects like bubbles, internal strains and extraneous matter. WebOptical flats made of quartz are often coated on one side, to give higher reflectivity. Optical flats are in the shape of discs, having parallel surfaces. Optical flats can be described as an optical grade glass, whic... Most optical flats are made out of quartz. Some are made out …
WebOptical flats can also be used as mirror substrates with particularly high flatness. Properties of Mirror Substrates Although the actual function of the mirror is performed by the mirror coatings, various properties of the mirror substrate, as discussed in the following, can be relevant in practice.
