UQG Optics

Dichroic Filters
UQG Dichroic coated filters are glass filters with thin films and dielectric thin films vacuum deposited on glass substrates. These include Dichroic Colour Filters and Dichroic beamsplitting colour separating mirrors. Both are similar but the Dichroic Beamsplitters are used at 45°.
Dichroic Colour Filters
UQG dichroic Colour Filters include addition and subtractive colour filters. Transmitting and reflecting certain regions of the visible spectrum. The filters are practically absorbtion free non fading and highly transmitting. The addive colour filters are available in red, green and blue, substantive colours yellow, magenta and cyan.

For less demanding specifications for general lighting we also supply a range of standard colours please see Colour Chart.

Colour Beamsplitter Mirrors 45°
These colour beamsplitting separating mirrors are absorption free inference systems of extremely hard, chemically resistant oxide films. They offer sharp separation of transmitted and reflective regions. They are non fading, have high saturation and easy to clean. They are designed for 45° angle of incidence, greater angles of incidence cause a reversible shift in the spectral transmission and reflection edge towards shorter wavelengths supplied in 3 colours, Red, Blue and Green.
