FROSTED DICHROIC GLASS COLOURS
The twelve most popular colours within the glass series are now available as a new
range of Frosted Dichroic Glass filters, enabling the lighting designer to add
colour and diffusion in the one filter. The diffusion within the filter softens the
light beam giving a more even and graduated lighting effect.
Frosted Colour Dichroic Filters are colour-coated on one side by a vacuum
deposition of metal film, and diffused on the other side (the no-colour version is
simply diffuse texture on one side). The diffusion creates a frost very similar to
LEE 251 Quarter White Diffusion, 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
o
C, allowing the colour to last for years without fading.
Frosted Dichroic Glass filters are available for MR16 (4.99cm) circular light
fittings with an integral holder.
