ALPAO Shack–Hartmann (SH) wavefront sensors (WFS) are the only range of WFS especially designed for Adaptive Optics.
Key features
They feature excellent performances to fit with every adaptive optics system. Sensitivity, speed and spectral range can be chosen depending on your needs. All ALPAO SHs perfectly fit with ALPAO DMs and ALPAO software and real-time computers.
