LiteSentry of Northfield, Minn., and Stress Photonics of Madison, Wis., have collaborated on the development, manufacturing, sales and service of anisotropy inspection systems as an option to the Osprey Distortion and Flatness Inspection System by LiteSentry.

The integration of stress photonics technology into LiteSentry’s Osprey 8+ will allow tempered glass fabricators to scan for anisotropy online after the quench process and detect the maximum reflective iridescence for every lite tempered. This allows for real-time adjustments to the furnace to reduce the reflective iridescence caused by anisotropy, according to the company.

The collaboration comprises two parallel inspection systems in one structure. The Osprey uses area scan CMOS cameras and reflected LED white light. The anisotropy option uses grey field polarimeter cameras by stress photonics and unique polarized transmitted light. The anisotropy inspection option is available on all Osprey 7 models, and is a standard feature on the Osprey 8+.
