SID4 WAVEFRONT SENSOR

Phasics' wavefront sensors are based on the Quadrilateral Shearing Interferometry technique.

Wavefront sensors have a wide range of applications across various industries. They are commonly used for optics testing and alignment, which includes tasks like measuring surface profiles or reflected wavefront errors, evaluating transmitted wavefront errors, and assessing modulation transfer function. Wavefront sensors also play a crucial role in laser and optical systems qualification and control with adaptive optics. Additionally, they are utilized in material inspection and quantitative phase imaging. Virtually all industries related to photonics can benefit from the use of wavefront sensors.
