Direct Electron – Direct Detection Cameras for TEMs
Innovation propelling discovery
Direct Electron designs and manufactures next generation detection cameras for TEMs (Transmission Electron Microscopes). Driven by innovation, their cameras are enabling users to push the frontiers of science.
Mission and Commitment
Founded in 2007, Direct Electrons mission is to continue developing ultra-high performance cameras for electron microscopy. Their products combine technological innovation with unique features. By adding in unprecedented levels of customer service, their clients acquire better images faster.
In doing so, they have pioneered Direct Detection Device (DDD) camera technology and those who have adopted the technology have enjoyed a competitive edge.
Direct Electrons progressive technology is a result of the power of partnerships. They work with public organisations, academia as well as industry, to understand their needs and develop a solution. By way of example, DDD technology was developed in conjunction with the University of California San Diego (UCSD) with support from the US National Institute of health (NIH)
