OBSERVING DEVICE AND FLUORESCENT LIGHT OBSERVING DEVICE

摘要

An image can be captured with a high resolution to improve an observing accuracy without excessively reducing a numeric aperture despite a smaller magnification. A microscope observing device comprising a light source for applying an exciting light or a lighting light to a specimen placed on a stage, an object lens disposed oppositely on the stage to magnify a fluorescent light or a reflection light from the specimen, an imaging lens for forming an image on the specimen magnified by the object lens, and an imaging means for picking up the image on the specimen formed by the imaging lens, wherein a mechanism for switching object lenses is provided along with a plurality of object lenses with different magnifications, and a mechanism for switching imaging lenses (5a, 5b) is provided along with a plurality of imaging lenses with different magnifications.
