Founded in 1985 by Alex Redner, an international authority in the field of strain analysis with over 35 years of experience, Strainoptics, Inc. specializes in stress measurement instrumentation and optical inspection equipment for the glass and plastics industries, as well as for research and teaching applications.

We also offer a wide range of technical services, including residual stress analysis, materials evaluation, applications engineering, custom solutions, and complete calibration and repair services for all types of polarimetry equipment.

Additionally, we provide basic and advanced training in the topics of photoelasticity and stress measurement, both at our headquarters in North Wales, Pennsylvania (USA), near Philadelphia, and at any customer location.
Strainoptics equipment is in use by the most respected names in the glass and plastics industry. You’ll find our patented SCA on-line stress scanners installed in major float glass plants around the world, and our GASP? polarimeter is the internationally recognized standard for measuring surface stress in heat-strengthened and tempered glass.

We offer the largest line of instrumentation, from hand-held strain viewers, polarimeters, and instruments for measuring roller wave distortion, to light transmission meters and PC-based on-line and off-line systems for stress and birefringence measurement.

If you're not familiar with stress measurement test methods or if you're not sure which instruments are suitable for your application, please contact us via e-mail, phone or fax for assistance. We’ll be glad to review your application and help you understand how stress measurement can become a most productive part of your quality control rountine.
