xHREMTM: HREM Simulation Suite

New Version (v5.0) is available now for WinHREM and MacHREM.
The STEM Extension now supports the GPU (for Windows and macOS).

xHREMTM (WinHREMTM/MacHREMTM) is a suite of the high-resolution electron microscope (HREM) simulation programs that will run under both Windows and Mac OS. The suite is composed of xHREM to simulate high-resolution Transmission Electron Microscope (HRTEM) images and the two options (Extensions) for Convergent Beam Electron Diffraction (CBED) and Scanning Transmission Electron Microscope (STEM), respectively. Please consult each catalog listed below for more information.
