 Green Electron Images 

Eric Condliffe is Principle Experimental Officer in the School of Earth and Environment (SEE), University of Leeds. He has 26 years of experience of operating electron microprobes and scanning electron microscopes. He was a prize winner in the 2002 Visions of Science photographic competition (
The SEE Electron Optics Unit is part of the Leeds Electron Microscopy and Spectroscopy Centre (LEMAS -, a shared facility based in the Institute of Materials Research (IMR), University of Leeds, U.K.
Technical Information:
The majority of the images were taken on a Obducat CamScan™ Series 4 SEM, and a few on a Cameca™ SX-50 electron microprobe, both belonging to SEE. A number of images were taken on the Leo™ 1530 FEGSEM owned by IMR. Specific thanks are due to John Harrington of IMR ( for permission to use this instrument in the very rare periods when it has been idle.
The Obducat CamScan™ 4 has SE, BSE and CL imaging plus a CamScan/HKL™ EBSD system and an Oxford Inca™ EDS. Digital image capture is by an Imaging Associates Spectrum Mono™ system producing grey scale images at a resolution of 1024x768 at 259 dpi.
The Cameca™ SX-50 microprobe has SE, BSE, three WDS spectrometers and an Oxford Inca™ EDS. The microprobe images reproduced here were all generated by stage scanning at 1024x1024 with a pixel interval of up to 10µm.
The Leo™ FEGSE is used primarily for topographic imaging, and has an Oxford Inca™ EDS and an Oxford EBSD. This system generates grey scale images at 1024x768 and 2048x1536 at 72 dpi.
All the images have been resampled to 300 dpi and converted to RGB colour mode. Corel™ PhotoPaint™ 11 was used to tweak contrast and brightness and to apply a mild sharpening filter where appropriate. PhotoPaint™ was also used to add false colour to some images.
