Abstract
A microscope apparatus includes a color temperature adjustment unit. The color temperature adjustment unit includes, in order from an incident side of light: a first polarizer that converts the light into linearly polarized light; a ¼-wave plate that converts at least light of a predetermined wavelength of the linearly polarized light into circularly polarized light, the ¼-wave plate being fixed in a predetermined orientation relative to the first polarizer; and a second polarizer that extracts a predetermined polarization component, the second polarizer being disposed to be rotatable relative to the first polarizer. A difference between a phase amount with respect to light of 435 nm and a phase amount with respect to light of 635 nm of the ¼-wave plate is 30 degrees or more.
