MICROSCOPE EPI-ILLUMINATION LIGHTING DEVICE AND MICROSCOPE EQUIPPED WITH SAME

摘要

PROBLEM TO BE SOLVED: To provide a microscope epi-illumination lighting device designed such that a diaphragm diameter is variable, easy handling and a cost reduction are achieved, an amount of illuminating light for observation in a dark view field is obtained to the maximum, and a specimen with no recess and projection is easily focused, and to provide a microscope equipped with the apparatus.;SOLUTION: The microscope epi-illumination lighting device includes: an illuminating optical system for emitting light from a light source 11 to a specimen S; and an observing optical system for condensing an observation image of the specimen S via an objective lens 6. The microscope epi-illumination lighting device is provided with a diaphragm device 15 having a vane diaphragm 21 for adjusting the luminous flux diameter of the illuminating optical system within the microscope epi-illumination lighting device 1, and adapted to selectively position the vane diaphragm 21 in a conjugating position P1 or P2 for the optical path of the illuminating optical system.;COPYRIGHT: (C)2006,JPO&NCIPI
