Description
First of all the HASO 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
HASO 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…).

Applications
Successfully used in the most demanding applications in optical metrology, microscopy, and laser diagnostics, the HASO BROADBAND performs multiple functions:
- Quantify the aberrations of an optical system
- Align the system to ensure that it performs at its best
- Predict the performance of optical systems in terms of focusing capability or imaging quality
- Quantify the effects of temperature and gravity on system performance
- Verify that the optics comply with specifications
- Measure directly the optical system’s wavelength dependency
- Drive a wavefront corrector to rectify system aberrations
- Check whether the optical mount overly distorts the optics
