Optical flats are made of
WebAn optical flat is a disk of high-quality glass or quartz. The surface of the disk is ground and lapped to a high degree of flatness. Sizes of optical flats vary from 25 to 300 mm in diameter, with a thickness ranging from 25 to 50 mm. WebAt Optical Filter Shop, we provide optical flats made from one of two types of material: Fused silica: Fused silica optical flats have low thermal expansion. They are also highly durable and abrasion-resistant, making them an excellent choice for high-wear applications. ZERODUR®: ZERODUR ® is a clear ceramic glass with low thermal expansion.
