OSPREY®25 TRANSMISSIVE DISTORTION
Key Application: Laminating Lines,
Extruded Sheet Plastic
Measures the transmitted distortion (refractive power) of flat glass and plastic sheets
Transmitted distortion is measured over 100% of the product in diopters.
Direct measurement of Refractive Power and Angular Deviation as defined in DIN 52305 §9.2 and §9.1
Real-time data on distortion and flatness immediately after extrusion, autoclave, or on a continuous web application
Built-in barcode scanner to track each part in the quality database
Certified to ASTM, ISO, EN requirements for optics
New Features for Surface & Edge Quality
- Surface quality check (Scratches, Spots, and much more)
- Edge chips
- Dimension check
- Logo position & quality check
- White haze
- Data matrix code interpretation
Setting the standard in quality control.
The Osprey® 25 is the only system on the market that measures both optical distortion and anisotropy while meeting and exceeding the requirements of leading architects and glass suppliers. Developed in partnership with Stress Photonics, the global supplier of optical stress analysis, our revolutionary detection measures anisotropy, flatness, and over 15 types of optical distortion.

Optical distortion in glass is caused by a lack of flatness
Using patented optics, high-speed cameras, and powerful algorithms, the Osprey 10 Distortion and Osprey 10 Complete measures all types of optical distortion NOT just roller wave or edge kink distortion.
| Roll wave | Bird’s eye* | Saddle bow* |
| Edge kink | Picture framing* | Oil-canning or bi-stability* |
| Local Bow* | Belly banding* | Soft-center* |
| Pocket or hammer distortion* | Edge lift* | Center kink* |
| Side kink* | Corner lift* | Vertical kink* |
Anisotropy causes iridescence. This occurs when unbalanced residual temper stress selectively reflects naturally polarized light such as blue sky or water reflections.
The Osprey 10 measures the rotation of polarized light in nanometers along with all types of distortion.
The Osprey10 Transmissive Distortion provides real time, on-line inspection of transmitted distortion (refractive power) of flat glass and plastic sheets.
OBR is a LiteSentry proprietary quality test coupled with a cutting-edge neural network design that recognizes bowed or bi-stable pieces of glass in real-time and displays results alongside other Osprey data before pieces are removed from the furnace unload table.
Anisotropy and distortion are NOT the same
Some inspection systems that measure anisotropy claim to be able to predict and measure distortion, however anisotropy and distortion are two very different properties that require different measurements to catch defective parts.
| Benefit | Improvement | Value | Annual Cost Savings |
|---|---|---|---|
| Quality Improvement | Reduce product returns | Avoid expense of $1,000-$20,000 per incident for repair or replacement | Typical $20,000 |
| Improved Yield | Reduce losses in downstream fabrication (IG and lamination) | Avoid losses of $50 per IG, $150 per laminate, 10 each per month | $24,000 |
| Improved Throughput | Better process control increases furnace efficiency | Up to 5% production gain of 630 sq meters (6,775 sf) = $4,750/month | $57,000 |
| Decreased Quench Break | Better process control decreases loss due to quench break | 1% production gain of 125 sq meters (1,355 sf) = $950/month | $11,400 |
| Reduced Labor | 100% machine inspection replaces off-line human inspection | Save up to 25% FTE (2 shift production) | Up to $25,000 |
| Greater Customer Satisfaction | Higher quality product; more positive market perception of company | More competitive bids; opportunities in new, high-margin markets | $$$$$ |
Assumptions based on data from current Osprey users:
Typical replacement costs reflect a mix of residential, commercial, and industrial products
12,500 square meters (134,000 sf) per month typical production through tempering plant
Average total value of tempered product (including glass and tempering cost) = $10/square meter ($.95/sf)
Labor cost including salary and benefits = $50,000/year
