Dichroic Color Mirrors

High Transmission / Narrow Tolerance Dichroic Color Mirrors

Materion Balzers Optics shift-free color filters are dielectric coated interference mirrors which transmit certain regions of the visible spectrum and reflect others with the highest possible degree of efficiency. The mirrors are manufactured with the Materion Balzers Optics proprietary sputter technology which makes them extremely stable to changing operating temperatures and harsh environmental conditions.

Benefits

Sharp spectral separation between transmission and reflection with highest transmission and reflection values
Spectral stability at changing operating temperatures and humidity (shift-free)
Narrow cut-on/cut-off tolerances (≤1%) and excellent spectral uniformity
Highest scratch and mechanical resistance
Virtually absorption free for utmost transmission and reflection efficiency and minimum thermal stress
Aging and fading free colors with ultimate color saturation
Widest flexibility in custom designed colors, polarization planes, angles of incidence (AOI), substrate material and dimensions
Engineering support for custom designed color management systems
Available for use in transmissive mode as well as in reflective mode
Specification in CIE chromaticity coordinates with luminous transmission for projection display applications

Applications

Materion Balzers Optics color mirrors are used in color separation and recombination, mixing, and recognition systems. The most popular applications today are transmissive LCD projection display systems and film printers.
