What Direct Electron does
Direct Electron is a privately-held, San Diego-headquartered company that designs, manufactures, and sells direct electron detection cameras and supporting software for transmission electron microscopy (TEM). The company introduced the first large-format Direct Detection Device (DDD) in 2008 — building on sensor R&D that began in 2001 — and today fields a multi-product portfolio spanning cryo-EM (Apollo event-based camera), 4D STEM (Celeritas and Celeritas XS at up to 87,000 fps), general-purpose TEM (DE-16, DE-64 — the only true 8K x 8K direct detector), low-voltage EM (LV-16), and SEM/EBSD (SEMCam). Its software stack centers on the Mission Control acquisition suite with the Dimension module for 4D STEM and the DE-FreeScan scan generator accessory, all of which use open data formats (.tif, .mrc, HDF5) and expose a Python/C++/C# SDK.
The company serves primarily academic and research institutions conducting structural biology, materials science, and electron crystallography research — including UCLA, UC Berkeley, Caltech, University of Wisconsin-Madison, University of Glasgow, EPFL, and the Scottish Centre for Macromolecular Imaging. Revenue is generated through one-time hardware sales of high-value capital equipment (Apollo, Celeritas, DE-series, LV-series, SEMCam, sensor upgrades), one-time software licenses and add-on modules (Mission Control, Dimension), and recurring customer support services staffed by Ph.D. microscopists. Pricing is quote-based and not publicly disclosed, consistent with enterprise B2B sales.
Go-to-market combines direct enterprise field sales — with explicit "Request a Quote" and "Write a Grant" workflows on the website to support academic grant-funded purchases — and a regional-distributor channel for international coverage. The company has no disclosed venture capital or private equity ownership and operates as a Delaware limited partnership (Direct Electron, LP), with Robert Bilhorn serving as legal representative and President & CEO. Two recent U.S. Department of Energy awards (~$2.5M combined) supplement internal R&D funding rather than dilutive equity capital.
