Abstract

PURPOSE: To decrease the deflection of monitored picture by forming slight air current, in a direction crossing the optic axis of optical system, into a space between a pellet and the optical system to monitor through picture the upper surface of the pellet.
CONSTITUTION: A fan 3 is set to generate a layer-flowing slight air current, in a crossing direction against the optic axis 4 of a lens 2, between a pellet 1 and an object lens 2 of the optical system (microscope). The pellet 1 is carried to a fixed position on a heating block 5 by a supporter-lead frame to be heated to a fixed degree. The rising current generated at this time is blown off by the slight air current from the fan 3 to cause very little deflection of monitored picture.
