Permacolor™ 1012 Bright Straw Rosco Dichroic Filter

Rosco Permacolors are durable Dichroic glass color filters that transmit specific wavelengths of light and reflect the rest of the spectrum, rather than absorb it – which means colors that don't fade over time and increased light transmission compared to plastic color filters.  Manufactured using the highest quality coatings, Rosco Permacolor Dichroic Filters offer designers a long-life filter solution that is durable enough to withstand the extreme temperatures of moving-lights and architectural light fixtures. Permacolor Dichroic Filters are available in a palette of 60 standard colors.

• Permacolor filters are not recommended in fixtures¹ with a field angle greater than 40°.
• Not for use as a safety glass.  While high heat resistant, is not tempered or chemically treated.
• Temperature Rating² 200°C continuous, 450°C short-term (< 1 hour)
• Life expectancy of 10 years under normal conditions³

¹ Fixtures with beam spreads wider than 45° may exhibit color shifting at the periphery of the beam.  The wider the beam spread, the more significant the color shift will be.  This shift on the periphery can be alleviated with use of a donut, black foil, or use of a bezel.  This color shift is cosmetic only, and will not otherwise affect the performance of the filter.

² Dichroic filters are rated for continuous exposure to 200°C and short term (under 1 hour) exposure to 450°C temperatures.  A combination of factors such as lamp type, reflector type, reflector design, and position of the filter within the optical system determine the temperature of the filter.  Refer to the luminaire manufacturer's specifications for temperature measurements or perform your own tests as needed.

³ Long term exposure to high humidity or high temperature environments, may cause color shifts of ±5 nm.
