Schott Colour-glass filters Solid Colour Glass Filters are useful for wavelength selection absorbsion, and achieve much higher blocking densities than dichroics. The spectral transmission properties are uniform over the entire aperture of the Colour Glass Filter. A wider range of Schott Colour Glass filters are available, and the following thickness has been chosen for average blocking percentages in relation to filter type. If you require a different wavelength block, we can make a simple calculation in relation to the thickness to achieve your required wavelength. Our photonic filters (540FCS5050) are used with silicon detectors or cameras to adapt the spectral response to be approximately that of the ee.
