MultiZone PIR fresnel lenses are lens arrays used for PIR detection like intruder alarms or lighting applications. All lenses are made from infrared transmissive HDPE plastic for use in the 7..14 microns PIR wavelength band and are approx. 0.5 mm to 0.8 mm thick, depending on the model.

The application is in the smaller quantity range where a customer-specific lens is not worthwhile.

Colour: natural standard (opaque); light black (LB); white or grey on request
