The representative apparatus of the first group is the Laill microphotoraeter, Thile the Koch raiorophotonoter represents the second type, A schematic drawing of the Mull mi orophotometer is shorn on... the fig. 59. The light from an incandescent globe L, after passing through the oondensator C falls on the slit S2. Tfith the aid of the objective 02, an image of this slit is projected on the studied photographic plate H. A magnified image of thsifc part of the plate, covered by the image of the slit Sg, is in its turn projected on the second slit Si by the objective 01. The diaphragm, be . Ring the lit Si covers the thermo-element V, The width of the slits 8j. And S2 may be controlled in the same way as is done in spectroscopes.
