Osprey®5 Distortion Measurement System for Glass and Plastic
Patented

The Osprey®5  by LiteSentry™  is the world leading on-line measurement system for tempered glass.  First developed in 1999, over 100 Osprey®5 systems operate on tempering plants on 5 continents.

The Osprey®5 by LiteSentry™ Distortion Measurement System, launched in 2011,  provides the most current technology in  Optical Distortion measurement  in heat-treated glass and plastic.

The Osprey®5 provides true optical measurement in lens power (diopters) as seen by the customer!  The Osprey 5 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 and all other types of distortion.

Utilizing patented optics, high-speed cameras and powerful algorithms, Osprey®5 by LiteSentry™ is the industry standard.

  • Improves quality & reduces product returns. Real-time feedback allows furnace operator to improve process control.
  • Increases Throughput – Process control improves load utilization 10% to 33%.
  • Replaces labor consuming manual measurements required for inspection by  providing 100% inspection and compliance to ISO EN 112150-1 and ASTM C 1048 specifications.
  • Decreases scrap – Improves yield 1% to 2% with lower quench break and inadequate break pattern.

3 versions of the Osprey®5 available:

  • Osprey® HR (High Resolution) version
    available for solar module fabrication.
  • Standard version for architectural and
    residential glass fabrication.
  • Osprey CW for Continuous Web measurement for Plastic Sheet and Float Glass.

Features of the Osprey®5 Distortion Measurement System

Substrate

  • Clear, tinted (absorbing), hard or soft coat low E glass 0 to 19 mm thick
  • Inspection area width: 20 to 126 inches (500 to 3,200 mm)

Operator interface display

  • True millidiopter measurements
  • Distortion displayed in optical lens power (millidiopters) over full surface of each lite
  • Peak-to-valley (inches or mm) displayed for full length of glass, including leading edge, central area and trailing edge
  • Pop-up 3D visualization displays detail for any lite
  • Distortion is color-coded for ease of inspection (color thresholds user defined)
  • Trend graph of distortion over past 1-24 hours

Outputs
