HASO4 126 Broadband

High Spatial Sampling wavefront sensor

HASO4 126 Broadband

High Spatial Sampling wavefront sensor

Just like the HASO 126 VIS is the perfect 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, and a 350-1100 nm wavelength range providing a great versatility across applications from VIS-NIR to SWIR.

The HASO4 126 Broadband wavefront sensor

HASO4 126 Broadband wavefront sensor provides high-resolution and broadband for maximum precision and versatility. We offer a unique combination of expertise in high-quality microlens production, software development and accurate factory calibrations. This allows the HASO4 126 Broadband to provide high performance for applications requiring a high spatial frequency and very large dynamic range.

HASO4 126 Broadband is fully compatible with our Optical Engineer Companion platform and set of optical metrology tools

These include the R-FLEX2 and R-FLEX2 SWIR optical metrology platforms, and the R-FLEX LA and R-FLEX LA SWIR systems for various collimated beams from 35 to 150 mm (custom diameters available).


+ Quantify the optical system’s aberrations
+ Align the system to ensure that it performs at its best
+ Predict the optical system’s performance in terms of focalization capability or imaging quality
+ Quantify the effects of temperature and gravity on the system’s performance
+ Verify that the optics comply with specifications
+ Directly measure the optical system’s wavelength dependency
+ Pilot a wavefront corrector to change the system’s aberrations
