Title:
CONVERGING MIRROR FURNACE
Document Type and Number:
WIPO Patent Application WO/2013/081107
Kind Code:
A1
Abstract:
Provided is a converging mirror-based furnace for using a reflecting mirror device to reflect light sent from a light source to irradiate an object to be heated and heat the object to be heated, wherein the reflecting mirror device comprises a primary reflecting mirror and a secondary reflecting mirror, the light sent from the light source is reflected by the primary reflecting mirror and the secondary reflecting mirror in the stated order to irradiate the object to be heated, and the light which is reflected by the secondary reflecting mirror to irradiate the surface of the object to be heated is not irradiated perpendicular to the surface of the object to be heated. This makes it possible for a device that heats with converged infrared rays to be reduced in size with no change in heating performance, even with a device that uses revolving ellipsoids.
