Characteristic:
High Accuracy Measurement I The
rotary phase method is adopted as the measurement method, and highly accurate measurement is realized in any region independently of the measured value Δ (phase difference) value .
High Accuracy Measurement II The
phase plate uses a dedicated broadband phase plate, and high reproducibility can be measured by the rotation of the optical element by our proprietary Hall motor.
