Frameless Mirrors

Optosigma Frameless Mirrors are precision-coated mirror substrates supplied without a standard holder or mount, intended for OEM integration and custom optical assembly where the designer specifies the mounting interface. The substrate provides the reflective surface; the integrator controls the mechanical interface.

Substrate materials:
– BK7 borosilicate glass: standard for visible and NIR applications
– Fused silica: for UV and high-power laser applications with low absorption
– Zerodur: zero thermal expansion coefficient; for thermally stable laser cavities and interferometry

Coating types match the full Optosigma mirror catalog:
– Protected aluminum: broadband UV-NIR (250-900 nm)
– Protected silver: high reflectance visible-NIR (400-2000 nm)
– Protected gold: NIR-MIR and CO2 laser (above 600 nm, over 96% from 800 nm)
– Dielectric HR: laser-line high-reflectance coatings (over 99.5% R) at 355, 532, 1064 nm and other wavelengths

Sizes and shapes: circular, rectangular, and custom; thicknesses from 1 mm to 10+ mm depending on size and application.
