Abstract

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.

Description

technical field

[0001] The present invention relates to an observation device such as a microscope observation device and a fluorescence observation device for observing living bodies, organs, tissues, and the like. Background technique

[0002] Conventionally, a microscope observation device disclosed in Patent Document 1 has been known as a microscope observation device. The microscope observation device has: an objective lens arranged opposite to the sample; an imaging lens for imaging a magnified image in an imaging unit such as a CCD camera; A zoom relay lens that continuously changes the magnification inside.

[0003] According to this microscope observation device, the objective lens and the imaging lens are fixed, and even if the telephoto zoom relay lens is inserted and removed between them, the parfocal position of the imaging surface does not change, and the deterioration of the image due to zooming is small, and the Improve operability or performance.
