Dichroic Colour Blue Optical Filters

DICHROIC COLOUR BLUE FILTERS

UQG Optics shift-free colour filters are dielectric coated interference filters which transmit certain regions of the visible spectrum and reflect others with the highest possible degree of efficiency.

Technical Data

Angles of Incidence: 0° (±15°), other angles on request
Substrate material: Heat resistance borosilicate glass
Temperature stability: up to 350°C (mechanical & spectral)

Benefits

Sharp spectral separation between transmission & reflection with highest transmission & reflection values
Spectral stability at changing operating temperatures & humidity (shift-free)
Narrow cut-on/cut-off tolerances (<1%) & excellent spectral uniformity
Highest scratch & mechanical resistance
Virtually absorption free for utmost transmission & reflection efficiency & minimum thermal stress
Aging and fading free colours
Ultimate colour saturation
Widest flexibility in custom designed colours, polarisation planes, angles of incidence (AOI), substrate material and dimensions.
Engineering support for custom designed colour management systems
Specification in CIE chromaticity co-ordinates with luminous transmission for signal lighting applications
