Complete beam parameters metrology: Single-shot beam profiler + wavefront aberration measurement

Photonis, Xenics and El-Mul are now unified under the Exosens brand. Read more →

Based on its proprietary patented technology, Phasics' wavefront sensors simultaneously provide both phase and intensity measurements with unrivalled high resolution. The SID4 wavefront sensor combined with its beam-analysis software delivers a complete diagnostic of the laser: wavefront aberrations, intensity profiles, laser beam quality parameters (M2, waist size, and position, ...). The qualification is performed in a single-shot acquisition. Phasics' wavefront analyzer can be positioned at any point of the optical setup, whether the beam is collimated or diverging. The Phasics SID4 wavefront sensors are suitable for any laser, continuous or pulsed from UV to far IR, including broadband tunable sources, petawatt laser chains, etc.

Direct measurement of collimated and diverging beams

Direct measurement of collimated and diverging beams

The Phasics SID4 wavefront sensors are easy to use, and the integration on the optical setup is very flexible. Indeed, SID4 wavefront sensors can accommodate both collimated and diverging beams. No relay optics are needed: once the SID4 wavefront sensor is aligned, in a few clicks, you will get access to the complete laser parameters in a single-shot measurement.
