DM2 is an format produced by version 2 Digital Micrograph, a program used in 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. It was succeeded DM3 at some point before 1999[1]. There is no easily accessibly information about a "DM1" format, if it ever existed at all. It seems that Digital Micrograph version 2 was only for the (old) Macintosh platform.[2][1]

Identification
DM2 files have a type code of "GSHN" and a creator code of "GCCD".[3] Extrapolating from .dm3 and later, DM2 files would have the extension .dm2 if on a platform that uses extensions. This is directly claimed by dubious sources.[4] They will start with either 00 3d 00 00 00 04 00 00 00 C8 or with 00 3d 00 00 00 04 00 00 00 FA, for Digital Micrograph versions 2.0 and 2.5, respectively; they will start with 00 3d 00 00 00 04 regardless of version.[3]
