I guess that counts as portable, but damn would I love to have an electron microscope to play with.

The new instructor gets a hearty welcome

You’ve read, in both newspapers and magazines, about the powerful electron microscope. Now this amazing “instructor” of scientists and physicians becomes even more useful — in more research fields.

Through basic principles uncovered at RCA Laboratories, RCA engineers have developed a compact “table model” electron microscope, at a price which makes it practical for use in an increased number of universities, industries, hospitals, clinics. So simplified is the new instrument that a high school student or unskilled laboratory technician can quickly learn to use it!
