Knight Optical’s Colour Glass Filters for LED Lighting

22 Jun 2022

Knight Optical – the leading supplier of on-spec, metrology-tested optical components – has a wide-ranging portfolio of Colour Glass Filters available from stock or as made-to-order components

Popular amongst the entertainment and design industries – specifically within the LED lighting industry – our Colour Glass Filters are commonly used as downlights within stage production. Here, they filter different visible wavelengths and separate unwanted light from a white light source to provide that sought-after highly saturated, intense coloured light. 

Custom-Made Colour Glass Filters

Projects requiring tailored optical solutions can benefit from our custom-made Colour Glass Filters, in Longpass, Shortpass, Bandpass and Mounted varieties. This option allows you to specify millimetre-perfect dimensions, shapes, protective coatings and project-specific tolerances, ideally suited to your requirements. Custom-made Colour Glass Filters are also available with specific band-blocking coatings to optimise your wavelength of choice, and as alternative thickness substrates.

We stock a vast range of high-quality Colour Glass Filters, ready for next-day global dispatch. Our stock range includes Longpass, Shortpass, Bandpass and Mounted options; available in 25mm diameters, and x 3mm-thick 50 x 50mm squares.
