Mirrors/reflectors The following coatings are available:
high reflectance laser mirrors for one or more wavelengths
high reflectance laser mirrors with multiple auxiliary functions
partially transmitting mirrors
broadband mirrors with high reflectance
broadband mirrors with auxiliary functions such as cold light mirrors
metallic mirrors of Ag, Al, Au, Cu, Rh, Cr, Ni (unprotected or with dielectric protective overcoat or enhancing dielectric protective overcoat)
reinforced Ag and Al mirrors with long-term stability by surface hardening using IP technology
custom mirrors according to customer requirements
Nearly all types of mineral glass and crystal, as well as metal substrates (for metallic coatings) are suitable for coating.
The substrates are usually supplied by the customer.
If required, optical flats with high reflectance coatings can also be offered as complete solution.
wavelength range 0.19 µm to 5 µm (metallic mirrors: 0.2 µm to 12 µm)
for extremely demanding optical requirements
suitable for demanding substrate surface flatness specifications (achieved with compensation coating on rear with any desired optical function. Prerequisites: coplanar substrate, polished on both sides)
extremely low absorption and scatter losses
gas and water-free coatings for maximum performance, especially in NIR range (e.g. 2.94 µm)
deposition possible even on highly curved surfaces
long-term stability of optical and mechanical coating properties regardless of environmental influences (e.g. temperature, pressure, radiation)
highly resistant to thermal stress (up to 550°C on quartz glass or sapphire)
suitable for extreme environmental conditions (e.g. space qualified, salt water resistant) and large mechanical stresses (extremely hard and abrasion resistant)
