Dielectric mirror coatings

In comparison to metallic coatings they have higher reflection coefficient, better mechanical durability and they are laser radiation resistant. What is more, dielectrics do not phase shift the E vector orientation. But one should remember that the kind of coating is selected according to the demanded wavelength range and that the high reflection effect as well as other properties of the mirror depend on the angle of incidence and state of polarization.

Dielectric coated mirrors can be designed as single wavelength (laser line mirrors) or broadband ones. It is also possible to realize some special requirements for other spectral ranges.

VIS mirror, Angle of Incidence 0° VIS mirror, Angle of Incidence 0°
VIS mirror, Angle of Incidence 45° VIS mirror, Angle of Incidence 45°
UV mirror, Angle of Incidence 0° UV mirror, Angle of Incidence 0°
UV mirror, Angle of Incidence 45° UV mirror, Angle of Incidence 45°
