HASO™ EUV (Extreme UltraViolet) Shack-Hartmann wavefront sensors
 
  Imagine Optic's HASO EUV wavefront sensor, developed in partnership with LOA and the SOLEIL synchrotron, is the only device of its kind available that offers you the extreme precision and direct measurement functionality needed for today's demanding laboratory and industrial applications.
  • Synchrotron and X-FEL beam alignment and characterization
  • Micro and nano-beam focusing, automatic beam alignment, and high Strehl ratio for adaptive optics
  • Perfectly adapted for laboratory applications
  • Independent phase and intensity measurement
  • Insensitive to vibration

HASO-XEUVDesigned and built in collaboration with our customers and with their needs as the top priority, the HASO EUV incorporates our patented rotated square technology to offer high spatial resolution and wide dynamic range, making it the ideal choice for EUV lithography, synchrotron and X-FEL beam analysis.  When used for adaptive optics, the EUV becomes a powerful tool for that provides you with micro and nano-beam focusing, a high Strehl ratio and precise control of the focal spot shape.

When combined with our powerful and easy-to-use HASOv3, you can easily conduct wavefront acquisition and reconstruction.  Additional add-on modules offer features including extended wavefront reconstruction, PSF and MTF measurement, as well as an SDK core engine that enables you to build your own software applications in MATLAB, LabView or C++.

Applications include ultra short wavelength beam characterization, adjustment and alignment; adaptive optics and automatic beam alignment; and EUV lithography.
