STANDARD COLORS & CUSTOM DEVELOPMENT

Color, with a
technical foundation.

KUPO offers standard dichroic color filters and custom colors tailored to your project. We can analyze your target color spectrum to develop a customized filter that meets your requirements.

Published applications include stage lighting, architectural lighting, projection and fluorescence microscopy. Suitability depends on the complete optical system.

BEYOND THE SPECTRUM

Materials & specifications.

Dichroic family specifications · supplied catalog, printed p. 5
Coating Hard dielectric thin films; Ion Assistant Deposition (IAD), as described in the catalog
Spectral tolerance ±5 nm at T50% for normal production
Environmental test reference Humidity, adhesion and abrasion: MIL-M-13508C, as listed in the catalog

Substrate options

Catalog material information · printed p. 4
Substrate Listed thicknesses Catalog heat-resistance value
Borofloat glass 1.1, 2.0, 3.3, 3.8 mm Up to 450°C
Sodalime glass 1.1, 2.0, 2.9 mm Up to 150°C
Borosilicate glass (D263T) 0.21, 0.3, 0.55 mm Not stated

Source & review status

Transcribed from the supplied KUPO Dichroic catalog, printed pages 4–7 (PDF pages 6–9). Product visuals are newly created concept illustrations inspired by the filter families; evaluate actual samples for color and finish.

Reference names preserve the source spelling. Catalog graphs are family examples and are not presented as individual measurements for every color code.
