Frequently Asked Questions

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 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 are available in standard 12.5mm and 25mm diameter or 50mm square types. They can also be cut and edged to special shapes and sizes at short notice.

The transmission rate of dichroic shortpass filters is dependent on the type and substrate, but T Max=95% is typical.
