Molded Aspheric Lenses

LightPath’s glass molding technology has enabled high volume production of aspheric optics while maintaining the highest quality at an affordable price. Because molding is the most consistent and economical way to produce aspheres in large volumes, LightPath has perfected this method to offer the most precise aspheric lens available. LightPath offers standard and custom-made lenses, all designed by our expert optical design engineers.

  • Benefit from the quality and performance of all-glass aspheres
  • Easily transition from prototype phase to high-volume production
  • Customize to fit your application or choose from over 100 standard aspheric designs
  • RoHS-compliant, ultra-high quality glass

Our infrared collimating lenses are made from LightPath’s own BD-6 glass, which transmits very well from 2-14μm. These lenses are ideal for the collimation and focusing of quantum cascade lasers and other long wavelength laser sources. Standard and custom AR coatings are available.
