VARIOUS PIR ARRAYS
The various Fresnel Technologies lens arrays shown in the accompanying data sheets 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 radius about the sensitive
area of the detector. The detector position should be as shown, and centered left-right (see Figures 1–9).
The overall dimensions of the arrays are as shown in the data sheets. Their usual thickness is 0.015” ± 0.004”
(0.38 mm ± 0.1 mm). Border width is also as shown in the figures. Centering is held to 0.015” (0.38 mm) in both
directions, except for the EWA 0.3 GI V1, where it 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. Patents have been issued or are pending on several of the designs shown.
The various lens arrays shown in the data sheets are:

The mounting configuration for each array can be derived from a combination of its name and its data sheet.
The first portion of the name (e.g. WA) denotes the classification of the array (in the case of WA, wide angle). The
second portion denotes the focal length (i.e., the distance from the lens array to the active elements of the pyroelectric detector). GI or GO indicates that the array is designed to be used with its grooves toward or away from
the detector, respectively. If there is a number after GI or GO, it indicates the number of degrees of downward
tilt. If there is no number in that position, the array is meant to be used with no tilt. The final portion is the “version” or “type” of the particular array within its classification and focal length. Each data sheet indicates the
vertical position of the centerline of the pyroelectric detector with respect to the lens array’s border, and also
shows the preferred mounting height and downward tilt.
The data sheets of Figures 1–14 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, a mounting height of
3.3 feet (1 meter) for the animal alley lens array and the EWA 0.3 GI V1 and 6.8 feet (2.1 meters) for the others,
and downward tilts as shown in each array’s designation. CM 1.0 GI T1 is intended to be mounted on the ceiling, facing straight downward, at up to 49 feet (15 meters) from the floor. 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 1–9 will not apply.
