In photography with low powers (microcolinears of Voigtlander 
and planars of Zeiss) the arrangement of fig. 160 is convenient; the 
Microscope is removed, the objective n attached directly to the camera 
front board, and a large movable stage k attached to the camera. The 
■stage proper is of glass, supported by a metal frame. The coarse ad- 
justment is accomplished by moving the stage in the rod o, aDd is 
clamped in place by the screw p. The fine adjustment is by rack-and- 
pinion at l. The complete stage is detachable, and is fastened by the 
screw m.
