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 (3.5 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.81 (2.6 mm) below the upper edge, and centered left-right (see Figure 2). The overall dimensions of the arrays are 1.677 ±.1 (42.6 mm ±.3 mm) high by 2.42 ±.1 (61 mm ±.3 mm) wide by.15 ±.4 (.38 mm ±.1 mm) thick. Border width is approximately 1/8 (3 mm). Centering is held to.15 (.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 proprietary LODIFF lens patterns. 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: WIDE ANGLE ARRAYS WA 1.2 GI 12 V1 WA 1.2 GI 12 V2 WA 1.2 GI 12 V3 WA 1.2 GI 12 V4 WA 1.2 GI 12 V5 EXTRA WIDE ANGLE ARRAYS EWA 1.2 GI 12 V1 EWA 1.2 GI 12 V2 EWA 1.2 GI 12 V3 DENSE WIDE ANGLE ARRAYS DWA 1.2 GI 12 V1 DWA 1.2 GI 12 V2 LONG RANGE ARRAYS LR 1.2 GI 12 V1 LR 1.2 GI 12 V2 LR 1.2 GI 12 V3 PET IMMUNE ARRAYS WP 1.2 GI 12 V1 EWP 1.2 GI V1 ANIMAL ALLEY ARRAYS AA 1.2 GI 12 V1 AA 1.2 GI V1 AA 1.2 GI V2 AA 1.2 GI V3 VERTICAL BARRIER ARRAYS VB 1.2 GI V1 VB 1.2 GI V2 VB 1.2 GI 12 V1 Figures 3-3 illustrate the zone patterns for the arrays. The figures postulate a dual-element detector with 11 coverage both up-down and left-right, amplifier gain of about 5,, 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.21 (.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. f Copyright Fresnel Technologies, Inc. 29 www.fresneltech.com 9122
