A microscope apparatus includes: a light source configured to irradiate a specimen with illumination light; a revolver configured to hold plural objective lenses and arranges the plural objective lenses switchably onto an optical path; a sensor configured to detect an objective lens arranged on the optical path; a first illumination light quantity table configured to store therein a first illumination light quantity set for each of the plural objective lenses; a second illumination light quantity table configured to store therein a second illumination light quantity specified by an observer; an illumination light quantity setting unit configured to set validity/invalidity of the first illumination light quantity and second illumination light quantity; and an illumination controller configured to control light quantity of the light source to the first illumination light quantity or second illumination light quantity validated by the illumination light quantity setting unit.

Microscope apparatus

A microscope includes a light source, a condenser lens disposed on an optical path of the light source to illuminate a specimen, an objective lens disposed on the optical path on an opposite side of the specimen from the condenser lens, a first polarizing plate disposed between the light source and the condenser lens, a compensator disposed between the condenser lens and the first polarizing plate to adjust retardation of light transmitted through the first polarizing plate, a second polarizing plate for transmitting only one-directional polarization component of the light transmitted through the specimen according to a relative positional relationship with the first polarizing plate, a driving unit for changing retardation of the compensator, and a control unit for causing the driving unit to drive the compensator to increase or decrease the retardation within a range including a position where the retardation is zero as a reference.
