Product Overview

The 120-PERMA-2049 is a 1.95" round glass dichroic filter that is 1.75mm thick from Rosco that is made for lighting designers that require long-lasting, high-quality filters. Rosco Permacolor glass dichroic filters are durable, high temperature, high transmission glass color filters, that change the color of the light emanating from the fixture.

Permacolor filters withstand the heat of high temperature lighting fixtures like MR16, metal halide, and high wattage tungsten lamps thus making it ideal for use in permanent installations. Rosco Permacolor glass dichroic filters are manufactured to exacting tolerances in a state-of-the-art, physical vapor deposition system. This optimally sized manufacturing line allows for unprecedented control of color and film density. Permacolor filters are extremely durable and precisely repeatable, meeting the high expectations of entertainment and architectural lighting designers throughout the world.

Dichroic filters can be installed with either the coated side of the filter towards or away from the lamp. This may be application dependent. To determine the coated side of the filter, touch the point of a pen or pencil to the glass. If you are touching the coated side, the tip will appear to touch its reflection in the glass. On the un-coated side, the reflection appears with a small gap between the points.
