Optical switching apparatus for a reflected fluorescence microscope

摘要

An optical system switching apparatus for a reflected fluorescence microscope including a first turret having a plurality of first windows which are formed at an equal distance from a rotation center axis and on which absorption filters are mounted, a second turret having a plurality of second windows which are formed at an equal distance from the rotation center axis and on which excitation filters are mounted, a third turret having a plurality of mounting portions which are formed at an equal distance from the third rotation center axis and on which dichroic mirrors are mounted. The first to third turrets are assembled to be rotatable independently of each other, for optically aligning an arbitrary one of the excitation filters an arbitrary one of the dichroic mirrors, and an arbitrary one of the absorption filters at respective rotational positions.
