Dichroic Filters

Specifically designed to meet the demands of the lighting industry our dichroic filters are produced by the vacuum deposition of layers of thin metal films onto a substrate of borofloat glass or polycarbonate.

This production process creates spectacularly clear and pure colours that will not fade and are ideal for permanent installations.

Colour Correct Your LED Light Source

Our new range of dichroic filters use a polycarbonate substrate making them durable and highly versatile. At only 0.76mm thick these filters can easily fit within a small fixture accessory slot.

The filters have a dichroic coating on one side providing optimal colour correction for permanent solutions. The polycarbonate substrate provides a high heat resistance hard coating on both sides. 5 colours stocked in 49.9mm diameter (custom colours and sizes available).

Why LEE Filters Dichroic Polycarbonate?

“After experimenting with standard polyester gels, it became apparent to us that longevity was a significant issue with LED sources.

The bleaching of the dyes in the gels did not allow for permanent installation, which is a necessity in large scale architectural applications.

The dichroic coatings allowed us to access a range of architectural filters without worrying about fading, and the polycarbonate base material gave us the flexibility to customize bulbs in ways not possible with glass.”

Frosted Dichroic Glass Filters

  • Frosted Glass - Before

    Unfrosted Glass

  • Frosted Glass - After

    Frosted Glass

Diffusion within these filters softens the light beam giving a more even and graduated lighting effect.

All the colours within the glass series are available as Frosted Dichroic Glass filters, enabling the lighting designer to add colour and diffusion with one filter.

Frosted Colour Dichroic Filters are colour-coated on one side by a vacuum deposition of metal film, and diffused on the other side. The diffusion creates an even soft frost, removing the halo effect when the frosted side is placed on the fixture outwards, away from the lamp.

The dichroic coating is able to withstand temperatures up to 371°C, allowing the colour to last for years without fading.

Available for MR16 and PAR 16 circular light fittings as well as custom shapes and sizes.
