Shack-Hartmann wavefront sensors

The SHSLab wavefront sensor system is a powerful and comprehensive measurement solution for a multitude of optical applications, such as:

  • alignment of optical systems                     
  • measurement of imaging quality
  • surface shape measurement
  • laser beam characterization

It pairs the SHSCam wavefront sensor head with SHSWorks wavefront analysis software and delivers high speed, single-shot measurements with excellent accuracy.
