Abstract

PURPOSE:To remove stray light and widen the visual field of observation by reflecting the luminous flux deviated from a falling light illuminating device by transmitting or reflecting through or from a beam splitter thereby illuminating the specimen in the falling light illuminating device branched to the falling light illuminating device and an observing device by the beam splitter. CONSTITUTION:Light from a light source 1 irradiates a specimen 5 through a condenser lens 2 and a beam splitter 3. The reflected light frofm the sample 5 is observed through the beam splitter 3, an objective lens 6, and an eyepiece lens 7. On the other hand, these are so constituted that the light from the light source transmitted through the beam splitter 3 illuminates the specimen diagonally by providing a reflection mirror 4. Hence, the visual field wider than that by conventional falling light illumination is uniformly illuminated. Thereby, stray light is reduced and the visual field of observation is widened.
