PIR Fresnel Lenses
In a Fresnel lens, the outer refracting surface is compressed to a flat plane. The Fresnel lens is composed of a number of concentric grooves that refract light. A Fresnel lens can be designed to perform a number of functions, including focusing, energy collection, collimation and diffusion. These types of Fresnel lenses can be used in applications such as imaging, lighting, and passive infrared sensors.
Features:
- Designed for wavelengths between 5 and 20 microns.
- Peak transmission between 9 to 12 microns.
- Short focal lengths for low profile sensors
Optical surfaces are designed using Reflexite's proprietary design software.
PIR Lens Arrays
Reflexite manufactures a diverse group of Fresnel lens arrays for the infrared wavelengths. Our Passive Infrared (PIR) products are primarily used in the security and lighting control industries. We can design and custom manufacture lens arrays to meet your specific requirements.
PIR Lens Arrays - PIR motion sensor lens arrays are primarily used in motion sensor applications with a pyroelectric detector to create a detection pattern. There are a variety of models available, each creating a detection pattern with a specific range and viewing angle.
- Wide Angle Arrays
- Dense Pattern Arrays
- Short Focal Length Arrays
- Pet Immunity Arrays
- Ceiling Mount Arrays
Near Infrared Lenses and Lens Arrays
Reflexite has the expertise and capabilities to custom design and manufacture Fresnel lenses and lens arrays for near IR applications.
