Wisoptic’s optical mirrors are available for use with light in the UV, VIS, and IR spectral regions. Optical mirrors with a metallic coating have high reflectivity over the widest spectral region, whereas mirrors with a broadband dielectric coating have a narrower spectral range of operation; the average reflectivity throughout the specified region is greater than 99%. Hot, cold, backside polished, ultrafast, D-shaped, elliptical, parabolic, concave, crystalline, and laser line dielectric-coated optical mirrors are available for more specialized applications.
Dielectric mirror is an optical mirror made of thin layers of dielectric coating layers deposited on an optical substrate (UVFS or BK7). Dielectric laser mirrors are used 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.
Optical mirrors can also be grouped by shapes: spherical, rectangular, elliptical or tailored shapes.
