High-reflection Coatings
We offer narrowband and broadband dielectric high reflecting coatings as
well as a range of metal coatings. Laser Line HR Coatings are offered
for all major laser wavelengths in the range of 193 to 2100nm. Most of these
are listed in the following table but please call if you need a laser line
coating not listed. Broadband HR Coatings are offered for a selection of
bandwidths. They provide a very high degree of spectrally neutral reflection
and represent the ultimate in optical mirror coatings. Most of the coatings
listed are for use at 45 degrees angle of incidence, but we do offer a
selection of Broadband, Normal Incidence HR Coatings. Other normal
incidence coatings can be provided on special request.
Metal coatings, such as Protected Aluminum, Protected Silver or Protected
Gold provide a moderate level of reflectance over a very broad spectral
range. These coatings are protected by a thin layer of dielectric material in
order to make them durable. It is also possible to enhance the performance of
metal coatings by adding several dielectric layers over the metal coating.
