Plastic lenses trial system WPA-100-S

WPA-100-S is the specialized small measurement system for small lenses of less than about 10mm in diameter.
The software includes the automatic circle-area extracting function and the automatic acceptance function based on phase difference value.
It is useful for quality control of plastic lenses.

Displaying retardance and axis in real time

By using our original polarizing imaging sensor, distribution of retardance and axis are shown in real time. You can save the images as a movie file.

Quality evaluation of molded lens

Image of intensity
Image of retardance
It can be seen that the retardance, that is, birefringence is concentrated near the gate of the molded lens.
