PA/WPA Series features

Lens

PA/WPA systems are used in the process for improving the optical characteristics of plastic molded lenses for smartphones or for cameras embedded in car navigation systems, just to name a few examples.
High-speed measurement enables inspection of large product volumes in mass-production environments.

PA/WPA Series features

Film

The PA/WPA systems provides highly reliable detection of defects in transparent films, such as uniformity and fisheye defects. Furthermore, the utilization of high-retardation option enables evaluation of films whose retardation is as high as 10,000nm!

PA/WPA Series features

Glass

The evaluation of residual stress, resulting for example from bending or laser processing, is made easy by the various analysis functions encompassed with PA/WPA software.

PA/WPA Series features

Semiconductor

In addition to standard measurements, PA/WPA systems provide a set of functions specifically tailored to the detection of defects in a wide range of semiconductor wafers, such as SiC, GaN, sapphire, diamond etc.

Automobile

Birefringence in the plastic cover of speedometers and other onboard automobile equipment represents a major safety risk, as it causes visual artifacts impacting the visibility of the displays. Additionally, for the sake of weight reduction, more and more parts, including front, side and rear windshields, are being replaced by plastic molded parts, requiring an increasing focus on quality control of those parts. PA/WPA systems are the tools of choices to support the new needs implied by these trends.
