DIAPHRAGM ARRANGEMENT FOR GENERATING AN OBLIQUE ILLUMINATION IN A MICROSCOPE, AND MICROSCOPE

摘要

A diaphragm arrangement (100) for generating an oblique illumination in a microscope comprises a carrier element (130), an iris diaphragm element (110) having a variable iris diaphragm opening (111), a further diaphragm element (120) having a diaphragm opening (121) that, when it is in a first position relative to the carrier element (130), covers a portion of the iris diaphragm opening (111) and is mounted rotatably around a first rotation axis (A), such that a rotation of the further diaphragm element (120) around the first rotation axis (A) changes that portion of the iris diaphragm opening (111) which is covered by the further diaphragm element (120), and an actuation element (140) coupled to the further diaphragm element (120) via a coupling device (150) such that a rotation of the further diaphragm element (120) around the first rotation axis (A) is produced by an actuation of the actuation element (140).
