CM 0.77 GI VX
The lens arrays of Fresnel Technologies’ CM 0.77 GI VX series are intended to be used in ceiling-mounted passive infrared motion detector devices. They are used with the grooved side facing the pyroelectric detector, and
their mounting flange is intended to be 0.46” (11.7 mm) from the detector’s sensitive area, and centered about
it (see Figure 1).
The overall dimensions of the arrays are 2.066” ± 0.010” (52.5 mm ± 0.3 mm) in diameter by 0.310” ± 0.010”
(7.9 mm ± 0.3 mm) deep by 0.020” ± 0.004” (0.5 mm ± 0.1 mm) thick. The mounting flange is approximately
0.3” (7.8 mm) wide. Centering is held to 0.005” (0.12 mm).
Fresnel Technologies, Inc. is the premier manufacturer of Fresnel lens arrays. We have led the industry in the
development of new lenses and materials to advance the state of the art of passive infrared motion detection.
Our lenses and lens arrays have been incorporated into most passive infrared devices using refractive optics
since 1976. Our quality standards are the highest in the industry. Surface finish and inclusions are such that no
defect is visible at a distance of 3 feet (1 meter) under ordinary light. There are no functional flaws in our products whatsoever. Our POLY IR® infrared-transmitting materials are the best available in stiffness and in transmittance in the 8 to 14 µm region. Active lens segments are made from our acclaimed and proprietary LODIFF®
lens patterns.
We currently offer six types in this series: CM 0.77 GI V1, CM 0.77 GI V2, CM 0.77 GI V3, CM 0.77 GI V4 ,
CM 0.77 GI V5, and CM 0.77 GI V6.
Figures 2-14 illustrate the zone patterns for the arrays. The figures postulate a dual-element detector with 110°
coverage both up-down and left-right, amplifier gain of about 5,000, and a mounting height as shown in each
figure. Other detector arrangements can be used, and the use of detectors with a higher degree of circular symmetry, including four-element detectors with a square pattern, is encouraged. Assistance with zone patterns for
these detectors is available on request. If the detector you choose has a larger acceptance angle, the spacing
between the detector and the flange can be reduced by as much as 3 mm without significantly degrading the
performance of the central zones. This closer mounting will improve the outer zones and extend their range at
the 8’ (2.4 m) ceiling height.
