HASO3 WSR (Wide Spectral Range) is the latest addition to our award winning HASO product family. Available in two configurations, 32 x 40 and 58 x 74 microlenses, they combine the standard functionalities that customers have come to rely on, including absolute measurement, wide dynamic range, unequalled accuracy and insensitivity to vibration, with the capacity to measurement wavefronts across an exceptionally wide spectral band, even with monochromatic light.
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.
HASO3 WSR is ideally suited for applications including laser beam characterization (particularly adapted for frequency doubling), optical system metrology over a large spectral band, measuring the effects of chromatic aberrations and aligning laser optics.
