Fresnel Lens
Fresnel lenses use concentric grooves to provide efficient light collection and focusing with significantly less thickness and weight than conventional lenses.
Fresnel Lens Overview
Fresnel Lenses replace a continuous curved optical surface with concentric grooves, delivering effective focusing in a thin and lightweight form.
Chenyu Optics manufactures custom Fresnel lenses from optical acrylic (PMMA), polycarbonate and fused silica. Diameter, focal length, groove structure, groove pitch and optical performance can be customized.
UV and visible AR coatings are available to improve transmission efficiency for solar, lighting, projection and sensing systems.
