Wavefront sensors for Extreme UV
Imagine Optic’s HASO EUV wavefront sensor, developed in collaboration with the 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.
Designed 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 sampling and wide dynamic range, making it the ideal choice for HHG, EUV lithography, synchrotron and EUV-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 software packages, you can easily conduct wavefront acquisition and reconstruction. Additional add-on modules offer features including extended wavefront reconstruction and Point Spread Function (PSF), as well as a dynamic library that enables you to build your own software applications using this remarkable device.
Wavefront sensors for tender x-rays and soft x-rays
We can design the Hartmann sensor beyond the EUV, ex. for tender x-rays at 1.3 keV ( 0.9 nm)*. Such a wavefront sensor facilitates the alignment of Kirkpatrick-Baez systems. Influence functions of the mirror to wavefront or phase profiles can be easily obtained in order to optimize a focal spot. An example of delivered HASO energy range is 0.3-1.3 keV.
