Adaptive optics systems correct atmospheric turbulence in real time. Most adaptive optics systems used routinely correct in the near infrared, at wavelengths greater than 1 micrometer. MagAO-X is a new extreme adaptive optics (ExAO) instrument that will o er corrections at visible-to-near-IR wavelengths. MagAO-X will achieve Strehls 70% at H when running the 2048 high-order actuator deformable mirror at 3.7 kHz. A visible pyramid wavefront sensor (PWFS) optimized for sensing at 600-1000 nm wavelengths will provide the high-order wavefront sensing on MagAO- X. We present the optical design and predicted performance of the MagAO-X pyramid wavefront sensor.
