Fresnel Lenses Machining for Optical Tooling Components

Advantages of Precision Machined and Custom Fresnel Lenses and Fresnel Lenses.

Physically, the Fresnel lens has a narrow profile that focuses light similar to a conventional optical lens, but has several advantages over its thicker counterparts:

Light weight: a very interesting option in situations where weight is important (automotive, aerospace, etc.);
Large format: Fresnel lenses are very useful for standard and wide-angle applications;
Various substrate materials: substrate materials vary from acrylic to polycarbonate and glass.
Performance: excellent light gathering capability.
