'''DM2''' is an format produced by version 2 Digital Micrograph, a program used in [[Wikipedia:transmission electron microscopy|transmission electron microscopy]]. (Digital Micrograph version 2 is not to be confused with version 2 of Gatan Microscopy Suite ("GSM"), which Digital Micrograph was later subsumed into.) DM2 files contain data from the microscope, as well as a additional metadata, including a specification of how the image data should be displayed on a screen.
