Claims

[Scope of utility model registration request]

This image furnace has a thermal light source lamp placed at one focus of a reflecting mirror consisting of one or more spheroidal surfaces, and heats the sample placed at the other focus by concentrating the light. In the image reactor, the two core tube holders that hold the core tube from both sides move independently due to the pressing force of compression coil springs in the reflector, and the parts of the two core tube holders that come into contact with the core tube An image furnace characterized by having a hood that covers the outside of a cap of a furnace core tube, the hood having a depth sufficient to prevent direct light from a thermal light source lamp from hitting the cap of the furnace core tube.
