Simple Operation
High-Speed Operation

A very simple 3-step operation:
1.Insert the sample
2.Click on “measurement”
3.Data will display
As many as 5,000,000 data points are displayed (PA) within seconds.

PA/WPA Series features

A broad range of optional functionalities

Options such as change of field of view size, increase of the measurement range for high-retardation samples and various software analysis functionalities are available to extend PA/WPA, satisfying your needs.

Data Processing Function

Various filters, such as noise reduction or local variations enhancement etc., are provided to help your data analysis tasks. Configurable and multiple filters can be applied simultaneously.

Lens Analysis Function

Automatic detection of circular lens followed with OK/NG detection, based on user-based criteria related to statistics on the retardation and axis orientation within the lens area.

Real-time Decision Function


Real-time OK/NG decisions using criteria inherited from the lens analysis function (see above) are available. The resulting conformity information for each piece is displayed in real time, allowing use of this function for 100% inspection in high throughput environments such as manufacturing lines.

Real-time Analysis Function



Measurement time is virtually reduced to zero, as retardation information is displayed real-time at the camera refresh rate, and real-time refreshing of graphical functionalities allows getting statistical information at glance. This function is perfect for fast evaluation of pieces in high throughput environments, such as manufacturing lines.

High-Retardation Option

By changing the operating wavelengths, this option increases dramatically the measurement range of the WPA system, enabling evaluation of high-retardation materials.

Zoom Lens

This is an optional lens allowing zooming into smaller object that is too big to be evaluated with a microscopic type system.
It is optimal for smaller objects or to zoom into small areas of bigger objects, in order to dig into their detailed structures.

Chromatic Dispersion (CD) Mode

This option uses a different algorithm to evaluate retardation, by-passing the limitations which apply to samples that do not conform to a strict birefringence model (thick and/or complicated plastic molded parts, etc.), for which the standard algorithm tends to output erratic data.

Remote-Control Function

This is a software option to externally control the system, allowing to integrate the system into a larger manufacturing or testing infrastructure, for automated quality control.
