The Polymer Optics Cap Lens is designed for passive Infrared (PIR) motion detection.
The lens is available in two versions (i) domed and (ii) flat, and each variant has two beam configurations (a) 360 circular pattern and (b) horizontal curtain pattern.
There are numerous applications for these lenses, but one of the most interesting is within ceiling downlighters.
The PIR lens assembly is small and compact, and can easily fit between an LED array. The self-contained nature of the PIR assembly shields the pyro from unwanted heat and dust particles.
While the domed lens provides superior performance, the flat lens solution provides an aesthetic advantage, and for most downlight applications it would be the preferred choice.
