Transparent slits 5 cms. long, approximately 5μ wide and straight to within l line width were required. Lenses having the requisite resolving power do not have the necessary covering power. This paper describes a scanning microphotographic technique for greatly extending the length of line covered whilst retaining the edge delineation characteristics of microscope objectives. The design and construction of the apparatus is described, problems involved are discussed, and results shown. 相似文献
