10mm Dia. UV-Enhanced Aluminum Coated, λ/10 ZERODUR Mirror

Product Details Precision ZERODUR Substrates λ/10 Flatness Low Coefficient of Thermal Expansion TECHSPEC ZERODUR λ/10 First Surface Mirrors 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 λ/10 First Surface Mirrors feature precision polished substrates with λ/10 flatness and 20-10 surface quality. Multiple metallic and enhanced metallic coating options are available, allowing for these mirrors to be easily integrated into applications in both the visible and infrared spectrum. Note: Surface flatness is measured before coating.
