(1986). 19, 68 TV Display for JEOL TEM Range Now available for all JEOL transmission electron microscopes is a new low-light- level TV camera and display, which couples to a transmission screen below the internal microscope camera. With such a camera fitted, the range of TEM operation can be increased by lowering beam current to reduce specimen damage. In practice the beam can be so low that no image is visible on the usual fluorescent screen, yet the TV display shows all the image detail normally seen at higher current. With this reduction in specimen ex- posure, it is now possible to use the TV system to view thick samples or to mani- pulate contrast and extend into image storage, processing, analysis and re- cording of dynamic experiments. The scaling standard is 625 lines/25 frames/s, 2:1 interlace, so that many existing systems are compatible for fur- ther linking. JEOL (UK) Ltd, Jeol House, Grove Park, Colindale, London NW9 0JN.
