Concave Optical Mirrors

Front Surface Mirrors for Illumination Systems

LINOS® front-surface mirrors, made from premium Borofloat, are designed for advanced illumination systems that require stability and precise light control. They are well-suited for demanding illumination and laser applications, including DUV environments where optical performance and reliability are essential. Low-expansion substrates provide thermal and mechanical stability, maintaining alignment and minimizing deformation under changing conditions. Standard mirrors with front-surface aluminum coatings offer high reflectivity across the visible and UV spectrum, while aspheric mirrors enhance light distribution for specialized uses.
