Strainoptics Roller Wave Gauges are used for measuring roller wave in accordance with Glass Association of North America (GANA) and other accepted test methods. Measured peak-to-valley depth and wave length values are used to calculate optical distortion using a simple equation or supplied tables. Strainoptics offers five high-quality roller-wave models with ‘flat-bottom’ or ‘3-point contact surfaces’.
