615FDL12 - Dichroic Longpass Filters
Description
Longpass filters are designed to transmit wavelengths higher than the cut on point and reflect all lower wavelengths. These dichroic longpass filters consist of thin-film dielectric coatings on glass with sharp transitions between the transmitted and reflected bands. Having negligible absorption they are suitable for high powers and do not show the strong fluorescence of certain glass filters.
Our dichroic longpass 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 longpass filters have negligible absorption, making them suitable for high powers and not showing strong fluorescence like certain glass filters. They can be cut and edged to special shapes and sizes at short notice, mounted on diameters and squares, and are available in sets supplied in a wooden storage box for research and laboratory use.
Dichroic longpass filters are available in standard 12.5mm and 25mm diameter or 50mm square types. They can also be cut and edged for non-standard sizes to suit your application, with available sizes ranging from square 7mm-300mm and diameter 10mm-400mm.
The most frequently requested specifications for all dichroic filter types include available size, cutting tolerance, glass substrate, dichroic filter types, wavelengths, wavelength accuracy, and transmission.
Dichroic longpass filters are used to transmit wavelengths higher than the cut on point and reflect all lower wavelengths. They are commonly used in stage lighting and entertainment.
The transmission rate of dichroic longpass filters varies depending on the type and substrate, but T Max=95% is typical.
