Frequently Asked Questions

Dichroic bandpass filters are designed to transmit highly over a specific limited bandwidth while reflecting all other wavelengths. They are used in several different types of application including entertainment and stage lighting.

Our dichroic bandpass filters are available in a range of wavelengths and are supplied in standard 12.5mm and 25mm diameter or 50mm square types. They are also available in bespoke shapes to fit your requirements.

We offer longpass, shortpass, bandpass, bandblocking, hot and cold mirrors, IR and UV cut-off dichroic filters.

The transmission rate of the dichroic filters is T Max=95% typical dependant on type and substrate.

The wavelength accuracy of the dichroic filters is +/-5nm.
