SHSLab wavefront sensor applications

Alignment of optical systems
Alignment of optical systems: Wavefront guiding facilitates and speeds up your alignment process significantly.
Laser beam measurement
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
Optics testing: The precise measurement of the transmitted wavefront provides information on the Zernike wave aberrations and the corresponding PSF/MTF.

SHSCam family

SHSLab wavefront sensors consist of SHSCam wavefront sensor head and SHSWorks software. SHSCam wavefront sensors are available for different spectral ranges (UV, VIS/NIR, SWIR) and with different detection area and lateral resolution.
