Wavefront sensor HASO4 BROADBAND

HASO4 BROADBAND Wavefront Sensor First of all the HASO4 BROADBAND wavefront sensor is our most versatile . This newly-released second edition features the new SpotTracker technology. It also provides absolute wavefront and tilt information, eliminating alignment requirements. Providing outstanding performance, the HASO Wavefront Sensor family is besides that used in the most demanding applications in optical metrology, microscopy and also laser diagnostics worldwide. Further more, we offer a unique combination of expertise in high quality micro lens production, software development and also accurate factory calibrations. This allows the HASO4 BROADBAND to provide a level of performance beyond comparison for application over the full spectral range of silicon ( 350-1100 nm ). In addition to that it allows measurement up to 64 Zernike polynomials with individual accuracy better than 6nm rms. The SpotTracker provides easy HASO installation, and the capability to precisely follow absolute tilt/wavefront evolution over time. Last but not least, it provides λ/100 rms absolute accuracy on a huge dynamic range. In other words, it offers a patented wavefront correction algorithms for intensity beam variations (laser, Gaussian, hyper Gaussian, apodized beams…). Advantages Firstly, beam collimation with an accuracy better than 300m radius of curvature. Secondly, a 20 mm focal length measurement with a sensitivity of 1µm rms. Thirdly, direct wavefront acquisition of converging and diverging F/5 beams with an accuracy of about λ/100 rms including astigmatism and high order aberrations. At last, Control and adjustment of axial laser beam deviation better than 3 µ rad rms.
