Choose from digital flat-bottom, three-point contact, and edge-lift gauge models designed for flat glass quality control and inspection.
Roller wave distortion can occur during the heat treatment process, causing glass create visible ripples or optical distortion in reflected images. Strainoptics offers manually operated roller wave gauges and edge-lift gauges, in accordance with ASTM C1651, for measuring distortion in flat glass, supporting production control, incoming quality control, and inspection of heat-treated glass.

Measure roller wave depth in flat glass using digital or high-sensitivity dial options.

Use gauge models designed to support roller wave measurement in accordance with ASTM C1651.

Choose from flat-bottom and adjustable three-point contact gauge configurations.

Measure edge lift, edge kink, or edge curl to help reduce distortion and field failure risk.

The RWG-DF features a 16″ long delrin-coated base and LCD digital readout. It measures peak-to-valley roller wave depth in accordance with ASTM C1651 with a resolution of 0.01 mm / 0.0005″. A high-sensitivity dial option is also available.
The RWG-D features an adjustable three-point contact bottom surface and a battery-powered digital micrometer indicator. It measures peak-to-valley roller wave depth to 0.01 mm / 0.0005″ in accordance with ASTM C1651. A high-sensitivity dial option is also available.
The ELG-100 measures edge lift, edge kink, or edge curl in flat glass. It is ideal for production control and incoming QC of heat-treated glass and can also be used as a conventional flat-bottom roller wave gauge.
Protect your roller wave gauge in rough environments with a heavy-duty carrying case featuring protective foam packaging and the Strainoptics logo.
