[Also in Group XL (b)] An exposure meter for photomicrographic apparatus includes means for limiting the field of view of the meter to an area of interest and means for influencing the meter output in inverse proportion to the size of the field. Light entering a microscope objective 13, Fig. 5, is focused through a magnetically actuated rotaryvane shutter 21 on to a photographic film 23. A portion of the light deflected by a semitransparent mirror 19 passes through a filter 30, adjustable and fixed optical wedges 56, 55, an iris diaphragm 63 and a diffuser 31 to a photomultiplier. Iris 63 is adjusted by a disc 71 until it defines the area of interest in the microscope slide as determined by viewing an image of a coupled iris 67 superimposed on an image of the slide in eyepiece 14. Optical wedge 56 is coupled to iris 63 in such a way that, for constant brightness a constant amount of light falls on the photomultiplier. The optical wedges may be replaced by polarizers, involving more complicated coupling. In another embodiment, Fig. 3, the iris 63 is replaced by a fixed pinhole b movable into and out of the measuring beam. A neutral filter a passes the same amount of light as pinhole b for a given brightness. In a modification, Fig. 4 (not shown), filter a is omitted and motion of pinhole b into the measuring beam closes a switch to change the supply voltage to the photomultiplier or the capacity of a condenser charged thereby.
