ABSTRACT:
A well plate holding a specimen to be observed is placed on a fixed stage, and the specimen is observed through an objective lens disposed below the well plate. A well set on the optical axis is illuminated through transmitted illumination provided by a transmitted illumination device. The transmitted illumination device includes a plurality of LEDs disposed to form a ring shape, and a through hole is formed further inward relative to the LEDs. When injecting a reagent into the well being observed, the reagent is drawn by using a head at a pipette device, and then the head is moved to a point above the well being observed through the hole formed at the transmitted illumination device.
