Fresnel Lens

Fresnel lens : 

Fresnel lenses replace conventional  lenses that have a curved surface with a series of concentric grooves, which are moulded into the surface of lightweight plastic sheets. The moulded grooves act as individual refracting surfaces when viewed in cross section. These lightweight large-aperture Fresnel lenses are widely used as collimators and collectors.

Nirmal Optronics can offer Custom Fresnel Lenses and also offer other focal lengths and sizes from available alternative stock. A typical material used in manufacturing Fresnel Lenses is PMMA. Please find our standard Fresnel lens given in the below table.
