Abstract:
1. An inverted microscope comprising: a stage configured to have a specimen placed thereon; a light source unit which has a light source which irradiates light to the specimen on the stage; an objective lens which focuses at least observation light from the specimen on the stage; a body unit which holds at least the objective lens; a condenser which is provided on an optical axis of the objective lens; a condenser holding unit which holds the condenser; a condenser moving mechanism which movably supports the condenser holding unit and moves the condenser holding unit along the optical axis; a transmission mechanism which transmits power for moving the condenser to the condenser moving mechanism; an input unit which inputs the power to the transmission mechanism; a support column having a first end that is connected to the body unit, the support column extending in an extension direction that is substantially parallel to the optical axis; and an illumination support portion which extends from a second end of the support column in a direction substantially perpendicular to the extension direction of the support column, wherein the illumination support portion holds the light source unit and includes a reflection mirror provided inside the illumination support portion and configured to output the light from the light source unit to the condenser, wherein the transmission mechanism includes a timing belt configured to transmit the power to the condenser moving mechanism in response to operation of the input unit, and wherein the timing belt is provided inside the support column and the illumination support portion, and is disposed below the reflection mirror.
