High-range measurement for injection molding, optical film and much more. Monarch monitoring the retardation enables you to catch variations in the fabrication process of plastic molding products, or characterizing/comparing different manufacturing conditions. Providing quantity of feedback from production line, the WPA series can become a very useful process control to. Retardation in the gate area of molded lens significantly affects the loss of image quality and resolution. The WPA systems are a great help when searching for the optimum molding conditions to produce the smallest amount of retardation as possible in the lens gate area. With transparent films, the WPA system achieve the goal of providing simple and quantitative characterization of the retardation distribution. By adjusting the display range, very small irregularities can be identified and characterized in details. Small variations in axis orientation can also be easily caught.
