WebThe wedge between the surface of the work and the optical flat may be: Too thick. Press down on the optical flat with a uniform pressure to squeeze out the air film. Too thin. If moisture or oil is present if may cause the optical flat to wring or adhere to the work so closely that bands cannot appear. Too angular. 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. Working:
WebVarious materials can be used for optical flats including fused quartz, fused silica, Zerodur, Clearceram, BK7 and borosilicate. 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. WebOptical flats made from fused silica have a low thermal expansion. Fused silica is durable and maintains good resistance to abrasion. These types of optical flats are ideal for high wear applications. Additional mechanical, thermal, electrical, and chemical specifications are available for both fused silica optical flats and Zerodur optical ...
