Plano-concave Mirrors, Unmounted Fused Silica, RAL (AL)
Our unmounted plano-concave mirrors, made from high-purity fused silica, deliver stable, precise performance for demanding illumination and laser applications, including deep-ultraviolet (DUV) environments. Standard aluminum coatings are available, and advanced dielectric coatings can be tailored to specific spectral and power-handling requirements. Superior material quality minimizes scattering losses and ensures consistently high optical performance.
Tight focal-length tolerances guarantee reliable system integration and reproducible optical behavior across applications. To support efficient optical design and simulation workflows, comprehensive ZEMAX files are provided. For application-specific requirements or volume production needs, our team is ready to deliver customized solutions and provide a quotation aligned to your technical specifications.
