Frequently Asked Questions

The transmission rate of dichroic shortpass filters varies depending on the type and substrate, but T Max=95% is typical. They have negligible absorption and lack the strong fluorescence of certain glass filters.

The wavelength range of dichroic shortpass filters is 300-1200nm, depending on the type. They are available in longpass, shortpass, bandpass, bandblocking, hot and cold mirrors, IR and UV cut-off types.

Dichroic shortpass filters are made with a thin-film dielectric coating on glass. The glass substrate options include soda-lime glass, tempered glass, borosilicate glass, and borofloat glass.

Dichroic shortpass filters are available in a range of sizes, including square 7mm-300mm and diameter 10mm-400mm. They can also be cut and edged to special shapes and sizes at short notice.

Dichroic shortpass filters are used to transmit wavelengths lower than the cut off point and reflect all higher wavelengths. They are commonly used in stage lighting and entertainment.
