Filter Sheet, Red

Acetate colour filter sheets. Each sheet is supplied with a graph of its spectral absorption characteristics. Available in six colours - Primary Red, Primary Blue, Primary Green, Magenta, Cyan, and Yellow. Size: 535 x 310mm (L x W).

Q = What are the wavelengths of maximum transmission for the colour filter sheets?
A = The filters have maximum transmission at approx. the wavelengths below. Please note these values are not precise and with most of the filters there is more than one peak for maximum transmission of coloured light, or a range of wavelengths.
 Red 650 nm - 800nm
 Blue 450 nm & 800 nm
 Green 530 nm & 825nm
 Cyan 520 nm
 Magenta 500nm & 820 nm
 Yellow 530 nm - 820 nm
