Aspheric Lenses & Beam Combiners

CMM Optic aspheric lenses and beam combiners are cut and polished to precision standards using our 5-axis CNC diamond-turning machines.We have your needs covered with a wide array of available lens shapes, from standard parabolas to bi-conic lenses, including our build-to-print service for special customization. Lenses can be ordered with AR and IR coating options to complete the entire lens manufacturing process. 

Frequently CMM Optic aspheric lenses are used to eliminate spherical aberration in a laser system and to collimate light in optical fibers or laser diode light sources.

We create all of your diamond-turned aspherical lenses in our Troy, Michigan manufacturing site with our highly experienced technical team. Before shipping, our world-class metrology & inspection service will verify that your optics are as-ordered and ready to be sent to you.
