Abstract

208,775. Butterfield, H. G. Sept. 26, 1922. Photomicrography.-A photomicrographic attachment for photographic cameras consists of two telescopic tubes 4, 5 and is attached to or carries at its inner end a short, focus lens 2, and has at its outer end a stage 6 which supports the microscopic slide, &c. The inner tube 4 is secured by a milled-headed screw 3 to the thick central portion of a plate 1 which supports the lens 2, and which is screwed to the lens board 7 of the camera. The range of relative movement of the telescopic tubes 4, 5 is determined by focal length of the lens 2.
