Cryo-EM CTF & Thon Ring Simulator
Interactive 2D simulator of the electron-microscope contrast transfer function (CTF): tune defocus, spherical aberration and accelerating voltage, watch the genuine 2D Thon-ring power spectrum and live 1D radial CTF profile respond in real time, and fit defocus back from a clicked ring.
Explore the electron-microscope contrast transfer function as a live 3D surface: tune defocus, spherical aberration, accelerating voltage and envelope damping and watch the Thon-ring pattern and zero-crossing resolution respond in real time.
