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.

Measurement of retardance and optical axis of polarization-maintaining fiber


Retardance distribution along the dotted line.
The birefringence distribution of a small area can be visualized and quantified.
