集めることにより。It focuses and irradiates infrared rays, ultraviolet rays, etc. on the focal point of a reflecting mirror made of a geometrically curved surface with a focal point such as a removable curved surface.
For example, a light source 1 is placed at one focal point F1 of a reflecting mirror 2' having an elliptical curved surface as shown in FIG. By.
透明容器７′内に保持され、他方の焦点Ｆ２に置かれた
被加熱物８′を加熱する。An object to be heated 8' held in a transparent container 7' and placed at the other focal point F2 is heated.
従来の装置では反射鏡２′が金属等の不透明構造体で作

を観察することは困難であった。In conventional apparatuses, the reflecting mirror 2' was made of an opaque structure such as metal, so it was generally difficult to observe the state of the object to be heated 8' during heating.
加熱中に被加熱物８′の状態を観察する必要がある場合
には、被加熱物の近傍における反射鏡を無くす、例えば
半楕円曲面にする等の工夫が必要となり、反射鏡として
利用出来る楕円曲面の形状に制約があった。If it is necessary to observe the state of the object to be heated 8' during heating, it is necessary to eliminate the reflective mirror near the object to be heated, for example by making it a semi-elliptical curved surface. There were restrictions on the shape of the curved surface.
この様な方法で被加熱物のａ察を可能にした場合には、
集魚Ｆ２ に集光されずに拡散放射されてしまう光線が
多くなりエネルギーの無駄が生じる。If it is possible to detect the heated object using this method,
More light rays are not focused on the fish gathering F2 and are emitted diffusely, resulting in wasted energy.
この様なエネルギーロスの改善方法としては。Here are some ways to improve this kind of energy loss.
例えば公開実案公報昭５３−１５１４６７に開示されて
いる様に、補助反射鏡を設ける方法が知られているが、

う欠点がある。For example, a method of providing an auxiliary reflector is known, as disclosed in Japanese Patent Publication No. 53-151467.
This method has the disadvantage that the positions where the auxiliary reflector can be attached are limited, and only a portion of the diffused and emitted light can be relieved.
［解決しようとする問題点］
上述のように従来技術においては、反射鏡が不透明体で
あることから、光線照射時に被照射物の状態を観察する
には被照射物の近傍には反射鏡を設けられないという問
題点があり、このために楕円曲面等の利用率の低下をき
たし、従ってエネルギーの利用率が悪くなるという欠点
があった。[Problems to be solved] As mentioned above, in the conventional technology, since the reflecting mirror is an opaque body, in order to observe the state of the irradiated object during irradiation with light, a reflecting mirror must be placed near the irradiated object. There is a problem in that it is not provided, and this causes a decrease in the utilization efficiency of elliptical curved surfaces, etc., and therefore, there is a disadvantage that the energy utilization efficiency becomes poor.
本発明の目的は反射鏡にａ察用の窓等の欠落部分を設け

By coating the reflective surface with a thin film (for example, a thin film of gold, titanium oxide, etc.) that reflects infrared rays but transmits visible rays, the object to be irradiated (during heating) can be This makes it possible to observe the state of heated objects through a reflecting mirror.

光透過性により、反射鏡の内部で光線を照射されている
被照射物を観察することが可能で。Even if a reflecting mirror with a nearly perfect elliptical curved surface is used, it is possible to observe the object being irradiated with light inside the reflecting mirror due to the visible light transmittance of the reflecting mirror.
