The Rosco Laboratories Roscolux 120PERMA2160-64 is a 6.3" Round Permacolor™ Glass Dichroic Filter in Rosco #64: Light Steel Blue.

Rosco Permacolor™ Glass Dichroic 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.

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.

Rosco Permacolor dichroic glass filters are the perfect choice for designers requiring long-lasting, high-quality filters. Permacolor withstands the heat of high temperature lighting fixtures like MR16, metal halide, and high wattage tungsten lamps and are
ideal for use in permanent installations.

Rosco’s range of standard colors includes the bright saturated colors prone to premature fading in gel as well as a selection of pale tints and accent colors selected by leading architectural designers around the world.

Appropriate Luminaires
Determining whether dichroic filters are appropriate for use with a given fixture requires consideration of three different factors: filter size, beam spread and fixture wattage.

  • Beam spread
    Fixtures with beam spreads wider than 45Âş 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 such as Cinefoil or use of a bezel.
  • Heat
    Dichroic filters are rated for continuous exposure to 200ºC and short term exposure to 450º C temperatures. A combination of factorssuch as lamp type, reflector type, reflector design and position of the filterwithin the optical system determine the temperature of the filter. Refer tothe luminaire manufacturer’s specifications for temperature measurements orperform your own tests as needed.

Installation
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.

Color Frames
Whenever possible, dichroic filters should be mounted in frames designed specifically for glass filters. Contact the fixture manufacturer to determine if the appropriate holder is available. Rosco can supply holders for many typical theatrical fixtures as well as customized frames. In certain cases dichroic filters can be mounted within the lens assembly using heat-resistant silicon adhesive. UNDER NO CIRCUMSTANCES SHOULD DICHROIC FILTERS BE USED TO REPLACE THE MANUFACTURER’S INSTALLED SAFETY GLASS. Rosco’s borofloat substrate is a high-heat resistant glass but it is not tempered or chemically treated.

Manufacturing Information
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.

Description of Film Coating
All films are manufactured using dielectric materials (Ti02 and Si02) that are evaporated by an electron beam source in a high vacuum and
high temperature environment. This produces a dense film that is highly resistant to damage from abrasion, humidity, chemicals and spectral
radiation. Dielectric films are porous by nature. Long term exposure to high humidity or high temperature environments may cause color shifts of ±5 nm.

Rosco Laboratories Roscolux 120PERMA2160-64 Specifications:

  • Color: Rosco #64, Light Steel Blue
  • Dimensions:
    • Standard sizes: 6.3" round (160mm)
    • Standard Thickness:
      • 1.75 mm ±0.2mm
      • 3.3mm ±0.2mm
  • Cutting Tolerance: ±.25mm. Tolerance can depend on glass thickness or texture.
  • Temperature:
    • Maximum short term (< 1 hour): -50Âş C to 450Âş C
    • Maximum continuous (> 24 hours): 200Âş C
    • RTD < 90K (hot spotting)
  • Angle of Incidence: 0Âş to 45Âş
    Wavelength movement can depend on overall film thickness.
  • Color Tolerance: ± 5nm of designed Half Height
  • Surface Defects: 80 - 50 — Mil. O-13830 Scratch/Dig Test (.08mm Scratch or .5mm Dig per 20 sq. viewed by unaided eye with 40 watt source)
  • Adhesion: Passes Mil. C-48497 (Cellophane Tape Test)
  • Abrasion:
    Passes Mil. C-48497 (Moderate, 50 strokes with cheesecloth under 1 pound force, and severe, 20 strokes with coarse eraser under 2 pounds of force.)
  • Humidity: Passes Mil. C-48497 (95 - 100% @ 50C per 24 hour period)
  • Aperture: >95% (guaranteed usable area)
  • Transmission: Spectral distribution curves are available for all Permacolor filters. Contact your Sales Professional for specifics.

Disclaimer:
The statements regarding the above subjects are theoretical in nature and are assumed to be accurate. Testing for adhesion and abrasion was performed on a 3” x 3” sample of No. 3650, the thickest coating available in the Permacolor range and therefore most likely to fail during testing. Additionally, a “Torch Test” was conducted in which the coated surface of the filter was slowly heated with a propane torch until the substrate failed (~450º C) with no visible damage done to the coating. Rosco guarantees coating quality and all tolerance adherences at the time the product ships. We make no warranties on applications of use: site conditions, installation and handling, weather or climate conditions or other unknowns that may adversely affect and shorten the condition and lifespan of the glass and coatings
