Colour Glass filters are useful for selective wavelength absorption and therefore achieve high out of band blocking. Colour glass type Longpass filters have very low transmission in short wavelengths and high transmission in the long wavelengths. These filters are used in range of spectral selection scientific instrument applications.

The long-pass range of color glass filters listed here has uniform spectral transmission properties over their entire aperture. A wide range of Colour Glass Longpass Filters are available as 50x50mm and 25mm diameter filters, stocked in the options below.

Stock colour glass filters are available to purchase directly from this website. To enquire about our customer colour glass capabilities, or to place a custom order, please contact our technical sales team.
