XX 1.2 GI 12 VX
The lens arrays of Fresnel Technologies’ XX 1.2 GI 12 VX series are intended to be used in passive infrared
motion detector devices. They are optimized for dual-element pyroelectric detectors. They are normally used
with the grooved side facing the pyroelectric detector, and curved at a 1.2 inch (30.5 mm) radius about the
sensitive area of the detector (see Figure 1). In this case, the detector and the lens array should be inclined
downward at an angle of 12 degrees, for most of the types. The detector position should be 0.810" (20.6 mm)
below the upper edge, and centered left-right (see Figure 2).
The overall dimensions of the arrays are 1.677" ± 0.010" (42.6 mm ± 0.3 mm) high by 2.402" ± 0.010"
(61 mm ± 0.3 mm) wide by 0.015" ± 0.004" (0.38 mm ± 0.1 mm) thick. Border width is approximately 1/8"
(3 mm). Centering is held to 0.015" (0.38 mm) in both directions.
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 patented
LODIFF® lens patterns. The LODIFF® lens is covered under U.S. pat. Re. 35,534. Patents have been issued or
are pending on each of the designs in the XX 1.2 GI 12 VX series.
The members of the series are as follows:

Figures 3-23 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 of 3.3 feet
(1 meter) for the animal alley lens arrays and 6.8 feet (2.1 meters) for the others, and the 12° tilt for all arrays
except the animal alley lens arrays. The AA 1.2 GI 12 V1 is designed to be used at a height of 3.3 feet (1
meter) from the floor, in a unit which retains the 12° downward tilt. The AA 1.2 GI V1 and the AA 1.2 GI V2
are designed to be used at a height of 3.3 feet (1 meter) from the floor, in a unit which is not inclined when
mounted at this height but which is inclined downward 12° when mounted at the normal height of 6.8 feet
(2.1 meters). The AA 1.2 GI V3 is designed to be used at a height of 3.3 feet (1 meter) from the floor in a unit
which is not inclined downward at any mounting height. The VB 1.2 GI V2 is shown in a configuration useful
for personnel detection near a door, with the detector mounted so it looks down at the floor.
If you wish to use arrays from the XX 1.2 GI 12 VX series at a tilt angle other than 12°, you should move the
detector up 0.021" (0.53 mm) for each degree less than 12°, or down by the same amount for each degree
greater than 12°. The animal alley lens arrays discussed above are designed to be used at the angles specified,
so that this movement is unnecessary.
Other configurations (smooth side toward the detector, curved at other radii, tilted at other angles, etc.) can
be used as well, but the zone patterns illustrated in Figures 3-21 will not apply. As examples, we offer Figures
24-29, some of which illustrate various XX 1.2 GI 12 VX series arrays curved at a 1.2" radius but not tilted
downward 12°, and others of which show them held flat. Other examples are available on request.
