Osprey® 7 Distortion + Flatness Inspection System for Glass and Plastic


The Osprey 7 is the world leading on-line measurement system for tempered glass, and is the only measurement system in the world capable of meeting the requirements of leading architects, PPG Certified Fabricators, Guardian Select Fabricators, and suppliers to USA government contracts. First developed in 1999, hundreds of Osprey systems operate in tempering plants on 5 continents.  Launched in August 2016, Osprey 7 provides state-of-the-art technology in optical distortion measurement in heat-treated glass and plastic.

The Osprey 7 provides true optical measurement in lens power (diopters) as seen by the customer!  The Osprey 7 measures all types of optical distortion including roll wave, edge kink, local bow, pocket, side kink, hammer, bird’s eye, picture framing, belly banding, edge lift, vertical kink and all other types of distortion. Utilizing patented optics, high-speed cameras and powerful algorithms, Osprey 7 by LiteSentry™ is the industry standard.
