Ultimate performance wavefront sensor

The HASO3 128 GE2 Shack Hartmann wavefront sensor offers unique measurement performance capabilities with the following key features :

  • highest-resolution : 16,384 independent measurement points
  • largest aperture dimension of 14.6 x 14.6 mm²
  • simultaneous and independent measurement of both phase & intensity measurement
  • largest available dynamic range
  • temperature stabilized for long term measurements

The HASO 3 128 GE2 offers the highest level of performance ever achieved with a wavefront sensor. It has been used with success in the most demanding applications in optical metrology and laser diagnostics, It is the ultimate candidate for demanding optical metrology applications in science or the industry.

HASO 3 128 GE2 is delivered with WaveView, the 3rd generation of wavefront analysis software. With just a few clicks, you will get access to wavefront measurement, reconstruction etc . WaveView offers more than 150 functions and optional add-ons enable you to go even further and calculate the PSF, MTF, Strehl ratio and the M².

WaveKit (or Software Development Kit – SDK) will enable you to interface the HASO 4 Broadband with any kind of OEM products and systems.

On request, customized software solutions, perfectly adapted to your application case can be developed . Our engineering team will ensure sustainable product integration and maintenance for a long product lifetime.
