Industrial Shack-Hartmann sensors

 

The ShaH family of industrial Shack-Hartmann wavefront sensors is intended for a wide range of applications including fast and precise quality control of optical elements, airflow analysis, measurement of laser beam parameters, etc. The flexible design of the ShaH system allows optimizing the sensor parameters for a particular application. An advantageous feature of the device is the use of high-quality telescopes. This allows minimizing the influence of the angle of incidence of the analyzed beam on the instrumental function of the sensor. A special high-precision algorithm for locating hartmannogramm spots centers provides high accuracy of measurements even in difficult viewing conditions.
