FCT3 Series Tri-Lens for Cree XLamp 7090 XR and XR-E LEDs High efficiency 3 beams available MR-16 size tri-lens The FCT3 tri-lens offers low-profile lenses specifically designed for the XLamp (1) 7090XR and XR-E LEDs from Cree. A software-optimized aspheric profile enables the generation of three different beam output patterns: narrow, medium, and wide beams. The high collection efficiency reaches 85% of the total flux emitted by the LEDs. Lens holders are black polycarbonate, and provide the proper alignment between the LEDs and the lenses, and set the correct distance between the lens and Cree XLamp is a trademark of Cree, Inc. For technical LED. information about these LEDs please refer to the Cree XLamp datasheet or visit General Characteristics Lens Material Optical Grade PMMA Holder Material PC, black color Operating Temperature range -40deg C / + 80 deg C Storage Temperature range -40deg C / + 80 deg C Average transmittance in visible spectrum (400 700nm) >90%, as measured using 3mm thick Optical Grade PMMA. Please note that flow lines and weld lines on the external surfaces of the lenses are acceptable if the optical performance of the lens is within the specification described in the section OPTICAL CHARACTERISTICS IMPORTANT NOTE Lenses handling and cleaning: Handling: Always use gloves to handle lenses and/or handle the lenses only by the flange. Never touch the outside surfaces of the lenses with fingers finger oils and contamination will absorb or refract light. Cleaning: Clean lenses only if necessary. Use only soap and water to clean the surfaces and lenses. Never expose the lenses to solvents such as alcohol, as it will damage the plastic.
