Select the WFS according to your application needs.
For ophthalmology, microscopy and most application, ALPAO recommends an HASO 4 VIS wavefront sensor.
For atmospheric turbulence, fast and sensitive wavefront sensors are mandatory. ALPAO offers dedicated VIS and SWIR Shack-Hartmann WFS to astronomy and defense applications. With the most advanced EMCCD sensor, it features high sensitivity at a very fast frequency. The latency has also been optimized to fit the most demanding applications.
