ABSTRACT:
A mechanical indicator for indicating the intensity of an illuminator is described for use in an optical instrument. The indicator includes a cover plate having a plurality of apertures and an opaque slide plate mounted behind the cover. The opaque slide plate is connected to the apparatus controlling the lamp intensity and moves across the apertures as the lamp intensity is changed. A source of illumination is positioned with respect to the opaque slide plate so as to emit light through the apertures not covered by the plate.
