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 characterisation

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

SHSLab wavefront sensor applications

Alignment of optical systems: Wavefront guiding facilitates and speeds up your alignment process significantly.

Laser beam measurement: The single shot wavefront measurement allows for fast determination of laserbeam parameters, control of adaptive optics and thermal lens measurement.

Optics testing: The precise measurement of the transmitted wavefront provides information on the Zernike wave aberrations and the corresponding PSF/MTF.
