TECHSPEC® Precision Optical Flats are ideal for a variety of applications including interferometry, imaging systems, laser applications, optical path folding, and autocollimation. These mirrors are available in a variety of coating and substrate options, along with surface flatness options of λ/10 and λ/20. The first substrate option ZERODUR®, a yellow tinted glass ceramic, features an extremely low coefficient of thermal expansion and is the ideal choice for applications where temperature fluctuation is a concern. The second option, Fused Silica, is optically clear and features excellent resistance to abrasion and high durability, making it the best choice for applications in harsh environments.
TECHSPEC® λ/10 and λ/20 Precision Optical Flats are available for testing and measurement applications.
