HASO™3 FIRST Shack-Hartmann wavefront sensors
 
  Performance, value, ease of use!

Thanks to their compact size and Firewire connectivity, HASO FIRST wavefront sensors are surprisingly easy to deploy. They provide exceptionally accurate and reliable measurements at speeds up to 60 Hz by taking advantage of the HASO family’s unique features including:

  • patented technology that enables you to measure phase and intensity, both simultaneously and independently
  • true absolute measurement that lets you work without a reference beam
  • Dynamic Spot Tracking™ and Auto Spot Finder™ provide superior accuracy without compromising dynamic range
  • optimal optical quality refractive microlens arrays that, with our other features, eliminate crossing spot
  • insensible to vibrations

HASO-FIRSTThe all-new HASO FIRST is an ideal choice for results driven professionals in domains including adaptive optics, optical process optimization, laser beam characterization, and many others. These custom-calibrated, mono-wavelength (±50 nm) units enable you to build your very own high-quality wavefront metrology systems based on our patented Shack-Hartmann technology.

HASO FIRST is delivered with HASOv3, our industry leading wavefront analysis software. With just a few clicks, you can perform both zonal and modal wavefront reconstruction as well as visualize the spot image and raw camera data. Optional add-ons enable you to go even further and calculate the PSF, MTF, Strehl ratio and obtain the M² parameter.

Even more, HASO FIRST is ready for integration into your adaptive optics loop. Coupled with our powerful CASAO™ software package and a deformable mirror or SLM, you can correct and form wavefronts to optimize your beam’s shape and focal spot, or correct wavefront aberrations in microscopy applications ranging from bioimaging to nanolithography.

Technical specifications are detailed in the table below. If you would like more information on our HASO FIRST wavefront sensors, please call +33 (0)1 64 86 15 60 or e-mail us by clicking here.
