Optical Mirrors
• Narrow band laser line mirrors
• Board band dielectric/metallic mirrors
• Ultrafast laser mirrors
• High reflectivity mirrors
• High laser damage threshold mirrors
When classified by coatings, Optical Mirrors consist of dielectric mirrors and metallic mirrors. Dielectric mirror is an optical mirror made of thin layers of dielectric coating layers deposited on an optical substrate (UVFS or BK7). WISOPTIC offer dielectric laser mirrors for laser lines, for narrowband or broadband wavelength ranges covering spectrum from UV to IR. Metallic mirrors are coated with protected gold, silver, or aluminum. Metallic mirrors are widely used due to a moderate level of reflection over a very broad spectral range. Protected gold coatings have the highest reflectance in IR, protected silver is the most efficient in VIS, while protected aluminum is an economical reflector over entire 300nm-IR range. The top layer of dielectric material protects the metallic coatings and makes metallic mirrors durable and stable within long term of operation.
Optical Mirrors can also be grouped by shapes which could be spherical, rectangular, elliptical or custom shapes with flat, spherical concave or convex, or cylindrical surfaces.
WISOPTIC offers a large comprehensive selection of Optical Mirrors for use with light in DUV to IR spectral region, ranging from laser line mirrors, board-band dielectric/metallic mirrors to ultrafast laser mirrors. WISOPTIC make coatings design for mirrors under custom requests to provide ideal solutions for specialized applications especially at high laser power.
