Precision Aspheric Lenses are designed to focus light while eliminating spherical aberration from divergent light sources in applications including focusing the output of a laser diode. Aspheric lenses can increase the numerical aperture of a lens while minimizing system aberrations. Aspheric lenses may also reduce the number of elements needed in a multi-element system. Aspheric lenses can reduce overall system weight while providing advantages such as increasing throughput or simplifying assembly.
Convex Aspheric elements are used to reduce aberrations, apheric lens is ideal for light collection, projection, illumination, detection, and condensing applications.
VIS coating option provides less than 1.5% reflection from 425 – 675nm. NIR coating option provides less than 1.5% reflection from 600 – 1050nm. Contact us for volume pricing of the custom aspheric lenses.

FRP Mini-mesh Grating
FRP Molded Gratings are manufactured in an open and heated mold system. Continuous E-glass rovings are placed in the alternating mold layers and completely wetted out with resin. There are a number of different molds available resulting in an extensive range of panel sizes, thickness and mesh patterns.
