Dichroic Filters

Our Dichroic Filters are glass filters with thin films and dielectric thin films, vacuum deposited on glass substrates. Transmitting and reflecting certain regions of the visible spectrum, the filters are practically absorption free, non-fading and highly transmitting.

Dichroic Filters have a longer longevity than standard filters and as the light is reflected and not absorbed, there is less heating so are widely used in laser and imaging applications.

The 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.

UQG optics can provide stock sizes and custom made sizes with various coating wavelengths and material options.

Please contact our sales team.
