   Fresnel Lenses are optical lenses consisting of a series of concentric grooves etched into a plastic substrate. Each groove acts as an individual refracting surface, while the thin substrate minimizes the amount of light lost due to absorption.

   Our Fresnel lenses are effectively 1.5 mm thick across their entire diameter, and this uniform thickness, combined with the optical-grade acrylic substrate, reduces their weight by over 90% versus glass lenses of comparable focal length and diameter.*
