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.
