Kind Code:
A1
Abstract:
Provided is an optical device with which micro-imaging at a microscope level and macro-imaging at an overhead level, etc., are possible using a single optical system. This optical device captures images of objects and comprises: an imaging optical system 1a for forming images of objects; an imaging element 6 that converts images formed by the imaging optical system 1a into electric signals; and a magnification changing means that changes the imaging magnification of the imaging optical system 1a. The magnification changing means has a switching means that changes the magnification by switching between: a micro image forming mode in which a micro image of the object is formed on the imaging element 6 by the imaging optical system 1a; and a virtual mode in which a virtual image of the object is formed on the imaging element 6 by the imaging optical system 1a.
