Polariscope Stress Tester
Inspect residual stress patterns in transparent glass products.
A touchscreen polariscope for qualitative and quantitative residual-stress inspection of transparent glass and compatible plastic products.

Workflow and key features
The PGY-01A uses polarized-light interference and quarter-wave compensation to reveal stress-related birefringence. After specimen thickness is entered, it can calculate optical path difference and statistics, helping identify cracking risk and optical distortion.
- Qualitative screening and quantitative measurement modes
- Automatic angle and optical-path-difference display reduces reading error
- Adjustable light-field brightness supports different transparent samples
- Four-level permissions and audit trail support GMP-oriented laboratories
- Local storage and a micro-printer support on-site records
