Polymer Aspheres

Our stock polymer aspheres are ideally suited for prototyping to production. They are available uncoated or with broadband visible or near-infrared antireflection (AR) coatings, and custom coatings are available.


Silicone Optics

Our silicone optics are designed to handle the most extreme environments. Silicone's resistance to temperature, UV, and humidity and biocompatibility make it useful for lighting in the UV, VIS, and NIR. 


Passive IR Arrays

Fresnel Technologies offers six lines of standard PIR Fresnel lens arrays and an additional number of assorted types. We can also work through designing customized PIR lens array needs for your application.  


Fresnel Lenses

Fresnel Technologies offers a variety of stock Fresnel optical components to meet your needs. We can also design and construct custom items.
