Fresnel Lenses
Efficiently focus and aim light in circular fixtures like spotlights, downlights, and round highbays. Simplify your design with short focal length microstructred Fresnel optics, eliminating the need for large, complicated reflectors and lenses.
Typical response using LM215 in COB downlight.

These products are directional and should be installed with the microstructures (textured side) facing away from the lamp. If none of our standard products fit your needs, we have the capability to quickly prototype and develop custom optical solutions for you.
