Infrared Spherical Lenses
Coatings available, AR, High Durability AR, DLC, and Bandpass Filters
Materials: Ge, Si, ZnS, Chalcogenides, CaF2 and more
Sizes up to 350mm diameter
Overview
LightPath Technologies, through its subsidiary ISP Optics, has been producing spherical lenses for over 25 years. Manufactured in our ISO 9001:2015 and ITAR certified facility, LightPath uses multiple fabrication techniques including diamond turning, CNC and spindle polishing. We build to print or can customize components using a variety of IR materials and shapes (concave, convex, aspheric). Our lenses can provide even better performance with Diamond Like Carbon (DLC) or Antireflective (AR) coatings using our in-house CVD and PVD chambers. Every order contains QC documentation utilizing our extensive metrology capabilities.
