Observation apparatus having thermoregulation mechanism

An observation apparatus having an optical analysis feature of receiving light entering an immersion objective lens from an object of observation in liquid and a thermoregulation mechanism for the object of observation, comprising:

• a liquid receiving frame adapted to be fitted to the outer periphery of the immersion objective lens and provided with a liquid holding wall for holding immersion liquid supplied to immerse the immersion objective lens;
• and
• a heating device adapted to be fitted to the liquid receiving frame to heat the outer frame of the immersion objective lens;
• wherein the heating device includes:
• a heater section having a heat conveying section mounted in the liquid receiving frame, a heat moving member communicating with the heat conveying section and led out from the liquid receiving frame to the outside and a heat receiving body made of a magnetic body;
• and
• a heat supply section having an electromagnetic induction body arranged close to the heat receiving body of the heater section to supply electromagnetic induction to the heat receiving body and an electromagnetic induction power source for causing the electromagnetic induction body to generate electromagnetic induction.
