6″ Dia. Protected Aluminum, λ/10 Flat Fused Silica

Product Details Fused Silica and ZERODUR Substrates λ/10 and λ/20 Surface Flatness Variety of Coating Options Offered TECHSPEC Precision Optical Flat Mirrors are ideal for various applications, including interferometry, imaging systems, laser applications, optical path folding, and autocollimation. These mirrors are available in multiple coating and substrate options and 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. TECHSPEC Precision Optical Flat Mirrors are ideal for applications where temperature fluctuation is a concern using the ZERODUR substrate. 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. Please note, calibration certificates are not supplied with these parts. TECHSPEC λ/10 and λ/20 Precision Optical Flats are available for testing and measurement applications. Note: Surface flatness specifications are measured before coating.
