Imagine Optics’s new HASO4 Fast Shack-Hartmann wavefront sensors provide fast accurate and reliable measurements by combining a state of the art CMOS camera with the HASO line up standard functionalities that customers have been relying on for 2 decades : absolute measurement, unequalled accuracy, high linearity and insensitivity to vibration. The HASO4 Fast allows acquisition speed of up to 1 kHz and 16 x 16 sampling points.
When coupled with our WaveSuite software package, you can perform both zonal and modal wavefront reconstruction; calculate the PSF*, MTF* and Strehl ratio*; visualize the spot diagram; and obtain the M²* parameter. Adaptive optics users can take advantage of our WaveTune™ software package to control adaptive optics loops to compensate for atmospheric turbulence, optimize the focal spots of laser beams and Freespace communications.
