Adaptive Optics

SID4 V Vacuum


Phasics is innovating by proposing the first off-the-shelf vacuum compatible wavefront sensor on the market. The SID4 V is designed to perform wavefront measurements under high vacuum. the wavefront measurement is realized in-situ in the same condition as the experiment. Our new SID4 V vacuum wavefront sensor is also used to characterize laser beams after compression inside the compressor vessel. Finally, gas jet and plasma density are now measured as close to the target as possible.

BENEFITS: With Phasics’s unique strategy it’s now possible to correct the aberrations of every single optical element up to the target location inside the vacuum chamber.
