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.

Molded Glass Aspheric Lenses Information
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
- Ideal for laser diode and fiber modules
- High-NA to capture the full LD fast axis
- Variety of focal lengths offered
Machined aspheres: additionally, for small volumes and prototyping, we can manufacture CNC-machined or diamond-turned aspheres with our more than 20 asphere machines. These capabilities also extend well to large (>250mm) diameter aspheres.
IR molded aspheric lenses: for collimating quantum cascade lasers (QCL) and interband cascade lasers, we offer IR molded aspheric lenses made from chalcogenide glass.
Plastic aspheric lenses: for higher volume and cost-sensitive applications, we can mold plastic aspheres. These are ideal for consumer products incorporating lower power lasers. For imaging applications, we can also provide multi-element lenses incorporating plastic aspheric lens elements.
