Roller Wave Gauge and Edge-Lift Gauge – Strainoptics Instruments for Measuring Roll Wave Distortion in Architectural Glass
Strainoptics’ PS-100-C148 is the Polarimeter System you need to measure glass containers in accordance with ASTM C148 - Standard Test Methods for Polariscopic Examination of Glass Containers and C1426. The instrument is also sold with our RPLP-100 Full Wave Tint Plate. The Strainoptics PS-100-C148 Polarimeter System has a 200 x 200 mm viewing area and analyzer, which is calibrated in degrees for temper number. If you are measuring your glass containers in accordance with ASTM C148, this Strainoptics system is a must.
Contact us if you are uncertain if the PS-100-C148 is the best choice for your application.
Accessories such as tint plates, babinet or babinet soleil compensators, strain disc sets, microscopes, immersion cells, camera adapters, or other options can be used with most systems to suit the application.
Roller wave distortion can be visually observed in tempered and heat-strengthened glass. The heat treatment process can cause the glass to bow and warp, viewed as ripples or optical distortion of reflected images.
Strainoptics manufactures two basic types of manually operated roller wave gauges, the flat-bottom type and the three-point contact type. Each roller wave gauge can be used with test methods published by the Glass Association of North America (GANA) and ASTM C1651.
RWG-DF Digital Flat-Bottom Gauge
The RWG-DF roller wave gauge has a 16″ long delrin-coated base and an LCD digital readout. The RWG-DF measures peak-to-valley depth of the roller wave in accordance with ASTM C1651 with a resolution of 0.01 mm (0.0005″).
ALSO AVAILABLE WITH HIGH-SENSITIVITY DIAL (0.001 mm / 0.00005″)
RWG-D Digital “Three-Point Contact” Gauge
Adjustable three-point contact bottom surface equipped with a battery-powered digital micrometer indicator. The RWG-D roller wave gauge measures peak-to-valley depth of the roller wave to 0.01 mm (0.0005″) in accordance with ASTM C1651.
ALSO AVAILABLE WITH HIGH-SENSITIVITY DIAL (0.001 mm / 0.00005″)
ELG-100 Edge-Lift Gauge
Used for measuring edge lift (edge kink, edge curl) in flat glass. Ideal for production control and incoming QC of heat-treated glass. Controlling edge-lift reduces optical distortion and the chance of field failures in laminated units. Can also be used as a conventional flat-bottom roll wave gauge.
RWG Case
If you anticipate bringing your roller wave gauge into rough environments and want it protected, we offer heavy-duty carrying cases with protective foam packaging and the Strainoptics logo stamped right into it.
