An ecomonic wavefront sensor for the visible

HASO4 VIS Shack-Hartmann wavefront sensors are easy to deploy and ready for any application in visible spectrum.

The HASO4 VIS takes advantage of today’s best technology to provide unique features including:

  • 10 nm rms accuracy over the full visible spectrum (monochromatic or polychromatic)
  • optimized for large wavelength range (400-700 nm)
  • patented measurement of phase and intensity, simultaneously and independently
  • patented microlens array technology manufactured in-house
  • frame rate of 99 Hz, full-resolution
  • WaveView, the industry’s most complete software package, included
  • WaveKit SDK compatible with C, LabVIEW and MATLAB
  • C-mount compatible entrance aperture – external trigger capability

The HASO 4 VIS delivers accurate, reliable and fast measurement over the Visible (400-700nm) spectrum. This HASO offers 10nm rms absolute accuracy and large dynamic range over the visible range and comes at a very attractive price. This HASO is based on a camera offering the best industrial standards in term of reliability, and high wavefront measurement performance thanks to the unique characteristics coming with each of our products : factory calibration, advanced software and high quality hardware.

The HASO 4 VIS is an interesting option for OEM applications or as a relevant first step in wavefront sensing.

HASO 4 VIS is is delivered with WaveView, the 3rd generation of our wavefront analysis software offering more than 150 functions and optional add-ons offering advanced determination of PSF, MTF, Strehl ratio and M². Available as an option, WaveKit (or Software Development Kit – SDK) will enable you to interface the HASO 4 VIS into any custom systems. Customized software solutions, perfectly adapted to your application case can be developed on request. Our engineering team will ensure sustainable product integration and maintenance for a long product lifetime.

Our technical support and engineering team provide is available for software and any questions related to the  integration of the HASO in its environment.
