All PIR detectors rely on an optical system to transmit a small amount of infrared radiation emitted by an intruder onto a pyro-electric detector. Using Holographic Optical Technology, Texecom have developed a series of detectors with the unique HOTLens - a laser tuned diffractive lens that has enormous improvement in its optical properties over Fresnel lenses or segmented mirrors. A HOTLens diffracts only infrared light leading to a greater transmissivity than conventional lenses. HOTLens has a uniform energy density, again improving catch performance and reducing false alarm.
