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

What is the transmission rate of dichroic shortpass filters?
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.
What is the wavelength range of dichroic shortpass 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.
What is the glass substrate used for dichroic shortpass filters?
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.
What is the size range of the dichroic shortpass filters?
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.
What are dichroic shortpass filters used for?
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.
