Diflex™ Broadband Dielectric Mirrors

All-Purpose Solution for High Reflectivity Mirrors

Materion Balzers Optics provides the best choice of broadband high reflectivity mirrors. Diflex™ mirrors are characterized by extreme reflectivity, low scattering and a wide acceptance range for the angle of incidence. The consistent and high reflectivity for any polarization covers the wavelength range between 320nm to 2000nm. Diflex™ mirror coatings are composed of metall-oxide layers. They withstand harsh environmental conditions and can be cleaned repeatedly.

Benefits

Consistent and high reflectivity over the full VIS and NIR spectral range
R > 99% for wide range of angle of incidence
Long-term shift-free spectral performance
High environmental stability
Wide flexibility in filter size

Applications

High-performance low-loss optical systems
Laser optics
Biophotonics
