10 x 10mm λ/10 ZERODUR Uncoated Mirror Substrate

Product Details Precision ZERODUR Substrates λ/10 Flatness Low Coefficient of Thermal Expansion TECHSPEC ZERODUR Mirror Substrates are well suited for applications where temperature fluctuation is a concern. The ZERODUR substrates have a coefficient of thermal expansion (CTE) of ±0.10 x 10-6/°C, which is an order of magnitude lower than most glass types. The low CTE allows these mirrors to have a consistent reflected wavefront, even when exposed to environments with varying temperature or illumination sources with changing intensity. TECHSPEC ZERODUR Mirror Substrates feature precision polished substrates with λ/10 flatness and 20-10 surface quality.
