Wavefront sensor HASO4 SWIR

HASO SWIR Wavefront sensor Providing outstanding performance, the HASO Wavefront Sensor family is used in the most demanding applications in optical metrology, free-space communication and laser diagnostics worldwide. The HASO SWIR is a wavefront sensor based on an InGaAs camera, offering high accuracy, large dynamic range and high-speed acquisition frequency. It features the new SpotTracker technology, providing absolute wavefront and tilt information and eliminating alignment requirements. Best for – Optical metrology – Adaptive optics applications such as long-range communication – Optimizing the alignment of complex systems – Light-source characterization Features Successfully used in the most demanding applications in optical metrology, laser diagnostics and adaptive optics, the HASO SWIR performs multiple functions : + Laser beam deviation control better than 3 µrad rms + Collimation diagnostic up to curvature radii over 300m + Live wavefront acquisition. Measurement accuracy lambda/100 rms guaranteed for beams down to F/5 + True tilt measurement, curvature, astigmatism and high-order aberrations quantification + 3D localization of a focal spot up to 0.1 μm rms and 1 μm rms for lateral and axial resolution, respectively (F/5 beam) + Ultra-shot exposure time for Gated version Examples of Applications of HASO SWIR Wavefront sensor Checking beam collimation with an accuracy better than 300m radius of curvature Direct wavefront acquisition of converging and diverging F/5 beams with an accuracy of about λ/100 rms including astigmatism and high order aberrations Control and adjustment of axial laser beam deviation better than 5µrad rms and many more
