FC Lens series
for Cree XLamp 7090 XR and XR-E LEDs
High efficiency
4 beams available
Easy assembly
The FC 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 several different
beam output patterns: narrow, medium,
elliptical, and wide beams.
The high collection efficiency reaches
85% of the total flux emitted by the LEDs.
Lens holders are available in black, and
provide the proper alignment between the
LEDs and the lenses, and set the correct
distance between the lens and LED.

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.
