Abstract
Abstract Apparatus for use primarily in an electron microscope for automatically marking a serial number and variable magnification indicia on the photographic plate record produced by the microscope. The system comprises two different image generators, one an electromechanical serial number counter and the other a micron marker generator for generating the magnification indicia. The separate images generated by each of the two generators are transmitted by parallel lens and mirror apparatus to the photographic plate of the microscope and recorded thereon simultaneously with the specimen image. Each of the parallel optical transmitting systems has a fixed objective lens and mirror set which receives the image from a respective generator and a projector lens and mirror set which is movable to enable it to project the image onto photographic plates of different sizes. Each such optical transmitting system is constructed so as to preserve the size and focus of the images projected from the two generators regardless of the position of the projector lens and mirror. The two image generators comprise a conventional serial number counter and an unconventional magnification indicia generator, the latter comprising an arrangement of bulbs and light transmitting rods which form a variable ''''micron marker'''' scale display consisting of two spaced parallel lines and a numeral or numerals indicating the scale distance between the lines in microns. The selective illumination of the proper bulbs and light transmitting rods for a particular display is accomplished automatically through an electrical circuit controlled by the magnification adjustment of the microscope.
