Adaptive Optics

Introduction

ACCURATE WAVEFRONT CORRECTION | with any deformable mirror


Our adaptive optics loop achieves the finest possible correction, up to last parabola aberration removal, thanks to the combination of our high resolution wavefront sensor and the deformable device that best fits your set-up. An insightful support resulting from many years of experience is provided from the loop design to its installation.

Introduction

Phasics adaptive optics loop corrects the focal spot aberrations, up to after the last parabola. Wavefront is measured with Phasics sensor and iteratively corrected thanks to a deformable optics. The loop is managed through the OASys control software module.

Set Up

► Our solution combines our high resolution wavefront analyzer with any deformable mirror.

Any deformable mirror is possible: any provider and any technology such as piezoelectric or mechanical deformable mirror. Insightful guidance for mirror choice and positioning is provided to fit your application.

 

Advantages

CORRECTION AFTER THE LAST PARABOLA
Without an additional device


  • Phasics wavefront sensor is the unique tool on the market that can measure diverging beam wavefront. So it can be placed after the last parabola and used to calibrate the full chain including aberrations generated by the last parabola. Thus the most perfect focal spot is obtained

HIGH RESOLUTION
Up to 300×400 phase pixels


  • Accurate correction calculation and fast convergence
  • High accuracy and repeatability 3D pointing
