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.
