450FDS25 - Dichroic Shortpass Filters
Description
Shortpass filters are designed to transmit wavelengths lower than the cut off point and reflect all higher wavelengths. Knight Optical's Dichroic filters are comprised of a thin-film dielectric coating on glass, resulting in sharp transitions between the transmitted and reflected bands. With negligible absorption, this type of filter is ideal for high powers and lacks the strong fluorescence of certain glass filters.
Our dichroic shortpass filters are available in a range of wavelengths and are supplied in standard 12.5mm and 25mm diameter or 50mm square types. We are happy to cut and edge filters for non standard sizes to suit your application.

Frequently Asked Questions
Dichroic shortpass filters are available in standard sizes of 12.5mm and 25mm diameter or 50mm square types. They can also be cut and edged for non-standard sizes to suit your application.
Dichroic shortpass filters are made of a thin-film dielectric coating on glass. The glass substrate can be made of soda-lime glass, tempered glass, borosilicate glass, or borofloat glass.
Dichroic filters are available in longpass, shortpass, bandpass, bandblocking, hot and cold mirrors, IR and UV cut-off types. The wavelengths range from 300-1200nm depending on the type.
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.
Dichroic shortpass filters have a transmission rate of T Max=95% typical depending on the type and substrate.
