Abstract

A Schmaltz microscope may be simplified by replacing the slit, condenser and conventional light source with a line filament tungsten lamp. In the classical light section (or Schmaltz) microscope, shown in Fig. 1, the image 10 of a slit 12 is projected at 45 degrees onto a surface 14 under test. By viewing the slit image through separate viewing optics 16, contours in surface 14 can be observed. The projector requires a lamp 18, a condenser 20, and a mechanical slit 12 or glass reticle. The slit, condenser and lamp can be replaced by a line filament tungsten lamp 22, as shown in Fig. 2. This ensures maximum brightness, and makes a simpler and more compact system. The size of the line image 24 is determined by the filament diameter and the projector lens magnification.
