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.

Dichroic bandpass filters are available in a range of wavelengths and are supplied in standard 12.5mm and 25mm diameter or 50mm square types. Bespoke shapes are also available.

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

Yes, dichroic bandpass filters can be cut down or edged to special shapes and sizes at short notice.

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