Tesla BS 242 E transmission electron microscope

Description

A transmission electron microscope allows analysing ultra-thin strips of slides with a maximum magnification of 30,000x. Observation using this type of microscopes is made using a beam of electrons instead of light, which enabled greater resolution than is achievable in a classic optical microscope. Such devices are widely used in natural science, allowing, for example, observation of cellular organelles, which is impossible with light-based microscopy. The model presented here was made in 1954 in the Czechoslovak Academy of Science, by a team of designers headed by A. Delong. It is the first miniaturised device of this type, which was designed to operate on a separate table, unlike previous free-standing models of large dimensions. Unit production of the device was done in CAN’s own workshops, and mass production was conducted by the Tesla factory. Manufacturer: Technika Slaboproudová, 1950s-1960s Inv.
