Custom 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. 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 reflectance over an extremely 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.
