Imaging apparatus for thermal analyzer and thermal analyzer including the same

A thermal analyzer comprising:

• a thermal analyzer main body having a section that is provided with an observation window through which a heated sample arranged inside the thermal analyzer main body is imaged;
• and
• an imaging apparatus comprising:
• an imaging device that is provided with a lens housing and a main body section;
• a holding section configured to hold the imaging device to have an orientation in which the lens housing is oriented toward the observation window, and the main body section is positioned on an opposite side of the observation window across the lens housing;
• and
• a cooling fan configured to provide airflow inside the holding section,
• wherein the holding section is provided with a cooling air passage having an intake portion and an exhaust portion,
• wherein at least a portion of the lens housing is arranged in the cooling air passage to be cooled by the airflow provided by the cooling fan, and
• wherein the exhaust portion is opened toward a tip end side of the lens housing in an axial direction and toward the observation window so as to surround outer circumference of the lens housing, and cooling air is discharged from the exhaust portion to the tip end side of the lens housing in the axial direction.
