An Image Intensifier and Polaroid Camera for the Tem
Ever since the transmission electron microscope was invented and introduced into the scientific laboratory as a working tool, there have been two features desired by most microscopists which have never been completely fulfilled by the manufacturers of the instrument at reasonable cost. The first, adequate intensity at all magnifications and sufficient illumination of the screen when viewing heat-sensitive specimens. A second most desired feature is instant photography of what is being observed on the fluorescent screen. These two desired features are now available by adapting on the shelf devices to the TEM.The first device is for intensifying the image normally viewed on the fluorescent screen for critical focusing, contrast enhancement for specimen scanning without burning up the sample by excessive electron bombardment or by increasing specimen contamination. A second device is a method of simple outside the column photography without image grain or distortion and without alteration to the normal operation of the electron microscope.
