Imagine Optic HASO 126 VIS Wavefront Sensor

Providing outstanding performance, the HASO wavefront sensor family is used worldwide in the most demanding applications in optical metrology, industrial control, microscopy and laser diagnostics. We offer a unique combination of expertise in high-quality microlens production, software development and accurate factory calibrations. The HASO4 126 VIS is the perfect Shack-Hartmann wavefront sensor for applications that require high sampling density or a very large dynamic range. It features the new SpotTracker system, providing absolute wavefront and tilt information and eliminating alignment requirement. This allows the HASO4 126 VIS to provide high performance for applications requiring a high spatial frequency and very large dynamic range.

Features:

• Easy setup on any beam size thanks to the large 13.8 x 10.2 mm² aperture

• Direct wavefront acquisition of converging and diverging F/5 beams with an accuracy of λ/100 RMS, including astigmatism and high-order aberrations

• Beam collimation with an accuracy better than 300 m radius of curvature

• Control and adjustment of axial laser beam deviation better than 3 µrad RMS

Applications:

• Quantify the aberrations of optical systems

• Align the system to ensure that it performs at its best

• Predict the optical system's performance in terms of focusing capability (PSF) or imaging quality (MTF)

• Quantify the effects of temperature and gravity on system performance
