FEI’s New Direct Electron Detector Revolutionizes Electron Microscopy of Biological and Other Beam-Sensitive Samples

Hillsboro, OR | Posted on July 27th, 2009

FEI Company (Nasdaq: FEIC), a leading provider of three-dimensional (3D) molecular, cellular and atomic-scale imaging systems, today announced the new Falcon™ Direct Electron Detector for its Titan™ and Tecnai™ transmission electron microscopes (TEMs). The Falcon is based upon direct electron detection that enables the acquisition of low-noise images of delicate biological samples and other beam-sensitive materials that require low electron dose interactions to prevent radiation damage of the material.

"We expect this new detector to revolutionize electron microscopy of biological structures," said Matthew Harris, FEI's vice president and general manager of the Life Sciences Division. "In these applications, imaging performance is limited by the inherently low contrast of the sample material and the samples' vulnerability to damage by the electron beam. The Falcon detector achieves signal to noise ratios equivalent to CCD cameras at a fraction of the electron dose. Conversely, at the maximum tolerable dose for a given sample, the Falcon detector delivers significant improvements in noise, contrast and resolution."

Limiting exposure to the electron beam is particularly important for biological samples that are primarily composed of a few relatively electron-sensitive elements and offer little intrinsic contrast in an electron microscope. Conventional fixing and staining techniques can improve contrast and dose tolerance, but introduce artifacts and increase the difficulty of image interpretation. Advanced cryo sample preparation techniques preserve biological structure but do not enhance contrast. The vulnerability of biological structures to damage by high energy beam electrons precludes the use of extended exposures that could otherwise be used to improve signal-to-noise.

The Falcon is a direct electron detector with improved quantum efficiency, capturing more information from a given electron dose, and accelerating the rate at which the signal-to-noise ratio improves over the exposure period. The unique design of the Falcon detector overcomes the excessive electron beam deterioration that was previously the primary technical challenge in developing a practical direct electron detector.

The Falcon detector offers 4K by 4K resolution and works in tandem with a CCD camera used for surveying and samples that are not dose sensitive. It is available for ordering in the fourth calendar quarter of 2009.
