Microscopy-Type Birefringence Measurement System WPA-micro

The microscope type.
WPA, this type, can be useful for the measurement and analysis of phase difference of samples such as, for example, a section of reinforced glasses and optical films, organic crystal coat and spherocrystal on a non-transparent substrate, and metallic crystal.

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.

*(1) The maximum range depends on the material being evaluated.
* Each specifications may be changed without notice.
* Inner deformation that can be measured with these series is measured optically, and measurement result value is represented as optical phase difference(unit: nm).
