Molded Optics Molded Aspheric Lens

Molded Glass Aspheric Lenses

Wavelength Opto-Electronic offers molded glass aspheric lenses in a variety of focal lengths. These infinite conjugate aspheric lenses can be used to either collimate a laser diode or other point source. As a laser diode collimator, these molded aspheric lenses are designed to produce a collimated single-mode beam with low wavefront error.

Each precision molded asphere is replicated from a long-lifetime mold for highly consistent performance. The replicated glass asphere molding process lends itself well to making lenses that are both high-performance and highly cost-effective.

Each molded asphere lens is AR coated to reduce reflections to the light source and increase transmission efficiency. Multilayer broadband AR coatings are available spanning three wavelength ranges: “A” (400-700nm), “B” (650-1100nm), and “C” (1050-1700nm).

  • Collimates or focuses laser light
