High performance wavefront sensor for the SWIR

The HASO SWIR is our Shack Hartmann wavefront sensor based on InGaAs camera offering high accuracy, large dynamic and speed over the SWIR 0.9-1.7um. It’ll be ideal wavefront sensor for optical metrology and adaptive optics with following key features including :

  • ~ λ/100 rms on the 0.9 – 1.7 µm wavelength range
  • simultaneous and independent measurement of both phase & intensity
  • true absolute measurement
  • large dynamic range
  • acquisition frequency up to 99 Hz

HASO SWIR is the ideal tool for optical metrology, adaptive optics applications such as long-range communication.

HASO4 SWIR 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  M².

WaveKit (Software Development Kit – SDK) will enable you to interface the HASO SWIRwith 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.
