INNOVATION

our passion is innovation

Working in partnership with academia and public/private institutions, Direct Electron continues to deliver a stream of innovations for TEM.

Our commitment to innovation delivers salient advantages to our customers:

COLLABORATION: We like to collaborate with our customers (either to generate new results or to develop new methods). We can work together with you to develop and implement new ideas and apply them to your specific research.
AHEAD OF THE CURVE: Our customers are confident that their camera represents the state-of-the-art technology for electron detection.
EARLY ACCESS: Our customers are the first to access and apply our new innovations in data collection techniques and image processing. In fact, many of our software innovations are free and open-source for our customers.
