Dichroic filters are durable glass color filters that transmit only certain wavelengths of light, reflecting the rest of the spectrum, rather than absorbing it. Since virtually no energy is absorbed by the filter, light transmission is significantly higher than traditional gels and will never burn out or fade. Rosco Permacolor filters are made with the highest quality coatings, designed not to fade or shift color. In addition, Rosco's sophisticated manufacturing process allows for precise color consistency batch to batch to a degree that is unprecedented in other dichroic coatings. Permacolor filters are manufactured in five standard sizes on durable borafloat glass 1.75mm (.069") thick or can be custom cut in any size up to 13.5" in diameter.

Standard Colors

Durable enough to withstand the extreme temperatures found in even the hottest luminaires, the Permacolor palette of standard colors offers designers a long life filter alternative to many of the most popular Rosco gel colors. Choose from among twenty four saturated colors that won't fade or burn over time.

This series of available colors has been designed with the assistance of architectural lighting designers around the world and is perfect for both interior and exterior architectural lighting projects. Subtle, pale color tints are perfect for accent lighting and offer a unique alternative to the typical bright saturated colors available from other dichroic suppliers.
