HASO™3 - 32, 42, 76, 128 wavefront sensors

HASO3 is the most recent evolution of our award winning HASO product line.  Based on our patented Shack-Hartmann technology, HASO3 wavefront sensors are easy to integrate and provide fast, accurate and reliable measurements by taking advantage of the HASO family's standard functionalities that customers have come to rely on, including absolute measurement, wide dynamic range, unequalled accuracy and insensitivity to vibration.

Our proprietary Dynamic Spot Tracking™ and Auto Spot Finder™ features combined with the exceptional optical quality of our refractive microlenses in our patented Rotated Square™ configuration provide superior accuracy and eliminate crossing spots, without compromising dynamic range.  Even more, Imagine Optic's proprietary calibration technology enables you to obtain absolute measurements every time, without the need for a reference beam, and our patented sensor design allows you to measure phase and intensity independently and in real-time.

For customers performing laser and optical metrology, your HASO3 sensor coupled with HASO v3 enables you to 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 CASAO™ software package to control adaptive optics loops to correct wavefronts, optimize the focal spots of laser beams and perform beam shaping.
