Rosco Heat & Therma Shield
SUPER HEAT SHIELD Rosco's Super Heat Shield Filter deflects heat from the color filter, minimizing the effects of high temperatures. Properly used, it increases the life of color filters in very hot fixtures without reducing light transmission.
Super Heat Shield deflects convected heat due to an extremely heat stable polymer base and properties inherent in its resin. Super Heat Shield is generally used to protect color filters in long range applications, especially when using dark colors such as blues and greens.
Super Heat Shield should be positioned between the lens and the color filter, allowing space on each side of the filter for the escape of heated air. Extenders which allow at least 1/2" of air space on each side of the Super Heat Shield will permit adequate venting and insure the longevity of the Super Heat Shield filter.
THERMASHIELD
Specially coated film reflects infrared energy to extend the life of color in super hot lighting fixtures.
Proprietary multi-layer coating reflects most of the infrared energy, thereby reducing transmitted heat
Allows the use of plastic color filters in fixtures equipped with MR's or other very hot lamps
Protects performers and products from heat of stage or quartz television lamps
When heat is a problem in television, theatre, display or architectural lighting, Thermashield is the answer. Thermashield lessens the adverse effects of heat on performers and products used in commercials. Where MR's or other hot lamps are used, it helps protect plastic color filters as well as other heat sensitive objects.
Rosco's Thermashield is an optical grade polyester film, finished on one side with a proprietary vacuum-deposited multi-layer coating. Set in the beam of a lighting instrument, it will reflect back infra-red energy, effectively reducing the transmitted heat, while transmitting 80% of the visible light.
It is important to allow air space between the Thermashield and the color filter. This will allow much of the otherwise damaging heat energy to dissipate. Its also important to affix Thermashield so that the coated side faces the lamp. Each sheet of Thermashield is clearly marked so that users can easily identify which side of the clear film should be facing the lamp. If the label becomes detached, or if the sheet is cut so that the label is no longer available, there is an alternative technique. When tested with an ohm meter, only the coated side (the side which must face the lamp) will be conductive.
Thermashield permits the full range of Rosco color filters in fixtures which previously permitted only the use of glass or dichroics for color. The maximum wattage lamps suitable for Thermashield filters are 1000 watt 120 volt or 1250 watt 240 volt Tungsten Halogen lamps. Thermashield will boost the Kelvin temperature of a 3200° source about 300° Kelvin (a mired shift of approximately -10). The material is available in 12" x 12" and 20" x 24" sheets.
