Our HASO Fast Shack-Hartmann wavefront sensors provide fast accurate and reliable measurements by uniting the standard HASO family’s standard functionalities that customers have come to rely on, including absolute measurement, unequalled accuracy and insensitivity to vibration, with an acquisition speed of 950 Hz and a spatial resolution of 16 x 16 microlenses.
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.
When coupled with our HASO v3 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 CASAO™ software package to control adaptive optics loops to compensate for atmospheric turbulence, optimize the focal spots of laser beams and Freespace communications.
