Abstract
With the aim of shortening the entire length and configuring an entire upright microscope compactly even if coded aperture technology and light field technology are applied thereto, a microscope pupil relay optical system is disposed on an image side of a microscope image-forming optical system including an objective lens, and includes, in the following order from an object side, a first lens group that has a positive refractive power and to which a convergent light flux is introduced from the object side; and a second lens group that has a positive refractive power. A lens located closest to the object-side end of the first lens group is disposed on the object side than a primary image-forming plane on which the microscope image-forming optical system forms an object image, and an exit pupil of the objective lens is re-formed at a position optically conjugate with the exit pupil.
