Iridescence & Retardance Inspection Systemfor Tempered Glass
Osprey 8 Anisotropy Inspection SystemIridescence & Retardance Inspection System for Tempered Glass
Developed in partnership with Stress Photonics, the global leader inoptical stress analysis for over 20 years, and designed for installationon any brand of tempering line.
Anisotropy — often seen as reflected iridescence — is a problem ofgrowing interest to architects, developers, and building owners. It is anatural result of the tempering process when unbalanced residual temperstress selectively reflects polarized light.
LiteSentry, with Stress Photonics offers Anisotropy Inspection withthe Osprey 8 Anisotropy Inspection System. The Osprey 8 Anisotropyis the industry standard for real-time inspection of tempered glass.The Osprey 8Anisotropyinspects foriridescence,heat staining,white hazeand retardationand more. TheOsprey provides100%Inspection.Offeringvisualizationandquantification ofthe mostchallengingproblems inglass fabrication.

Osprey 8 Anisotropy Inspection System
Iridescence is frequently visible when glass reflects the polarized lightof blue skies or water. In these situations, light that would naturallypass through the glass rotates, causing shimmering patterns whereglass stress is high and reflected, and dark patterns where stress islow and transmitted.

Osprey 8 Anisotropy uses Stress Photonics Grey-Field Polariscopecameras and polarized transmitted light to detect anisotropy effectsin every sheet of glass. The Osprey offers the most complete glassinspection system for measuring anisotropy in tempered glass.
