Colour Glass Filters are polished sheets of special glass that have been cast with a dye included in it. Colour Glass Bandpass Filters are generally relatively cheap and very stable. The disadvantage with them is that they are only available in a relatively small number of variants, and so can be restrictive in bandpass selection.  Interference filters are then the best option however a more expensive choice is. 

The filters listed here are of the band-pass type and have uniform spectral transmission properties over their entire aperture. A wide range of band-pass filters are available with circular filters of 25mm diameter and square 50x50mm filters. These filters are primarily used in applications such as agriculture analysis, medical analysers and fluorescence applications.

Colour glass filters also have high transmissions at selected wavelengths therefore ideal where the angle of incidence of the incident light cannot be tightly controlled.
