    摘要: A vacuum heating furnace comprises a translucent container for retaining a heated object and a heating light source for heating a heated object retained in the translucent container. The translucent container has on its surface a tapered portion to receive transmitted light totally reflected on the inner surface of the translucent container at an angle smaller than a critical angle.
