す。
As shown in FIG. 2, an inspection device 1 for an illumination meter 4 serving as an infrared detector has a window plate 3 provided in front of a light source body 2 and having an aperture a. Light (infrared rays) emitted from the light source main body 2 passes through an aperture a that sets the shape of the light source pattern, and serves as a light source for inspection. In the figure, 5 indicates a detector of the illumination meter 4.
上記従来の装置では、光源本体から発せられた
光が窓板３に到達する際、アパーチヤａを通過す
る光と、アパーチヤａ以外の部分にて通過を妨げ
られる遮断光とに分けられる。遮断光は窓板３を
加熱しその温度が上昇する。従つて、窓板３が雑
音光源となり不要な光を発していた。
In the conventional device described above, when the light emitted from the light source body reaches the window plate 3, it is divided into light that passes through the aperture a and blocked light that is blocked from passing through the aperture a. The blocked light heats the window plate 3 and its temperature increases. Therefore, the window plate 3 became a noise light source and emitted unnecessary light.
この検査装置１を使うと、照度計の検出器５は
光源本体２からの検査用の光ｃ以外に、熱せられ
た窓板３から発せられる光ｄを受光していた。 When this inspection device 1 was used, the detector 5 of the illumination meter received the light d emitted from the heated window plate 3 in addition to the inspection light c from the light source body 2.
すなわち、従来の検査装置１は本来の検査用の
光以外に雑音を出していた。 That is, the conventional inspection apparatus 1 emitted noise in addition to the original inspection light.
本考案は上記課題を解決するため次の手段を講
ずる。
The present invention takes the following measures to solve the above problems.
すなわち、赤外線計測器の検査装置として、光
源と、光源の前方に同軸に設けられ、かつ冷却用
の流体通路を有するアパーチヤ付の窓板と、同流
体通路に冷却用の流体を供給する冷却装置とを設
ける。 That is, as an inspection device for an infrared measuring instrument, a light source, a window plate with an aperture provided coaxially in front of the light source and having a cooling fluid passage, and a cooling device that supplies cooling fluid to the fluid passage. and.
上記手段により窓板が、冷却用の流体で冷却さ
れるので、窓板で遮断される光によつて、窓板は
高温にならない。従つて窓板から雑音となる不要
な光を発することもなくなる。
Since the window plate is cooled by the cooling fluid by the above means, the window plate does not reach a high temperature due to the light blocked by the window plate. Therefore, unnecessary light that causes noise is no longer emitted from the window board.
このようにして、本来の検査用の精度のよい光
を発するようになる。 In this way, highly accurate light for proper inspection can be emitted.
本考案の一実施例を第１図により説明する。な
お、従来例で説明した部分は、冗長さをさけるた
め説明を省略し、この考案に関する部分を主体に
説明する。
An embodiment of the present invention will be explained with reference to FIG. Note that the explanation of the parts explained in the conventional example will be omitted to avoid redundancy, and the explanation will mainly focus on the parts related to this invention.
検査装置１ａ内には光源本体２が設けられる。
光源本体２の前方にアパーチヤａ付の窓板３ａが
光源本体２の軸と同軸に設けられる。また窓板３
ａ内にはアパーチヤａの周りに花弁形の流体通路
６が設けられ、冷却装置７から冷却用の流体が供
給される。 A light source main body 2 is provided within the inspection device 1a.
A window plate 3a with an aperture a is provided in front of the light source body 2 coaxially with the axis of the light source body 2. Also window board 3
A petal-shaped fluid passage 6 is provided in the aperture a around the aperture a, and cooling fluid is supplied from a cooling device 7 to the petal-shaped fluid passage 6.
以上の構成において、検査用の光ｃを出すと
き、冷却装置７より冷却水を流体通路６に流す
と、窓板３ａは冷却される。従つて高温になら
ず、不要な雑音となる光を発しなくなる。このよ
うにして精度のよい光を出すようになる。 In the above configuration, when the inspection light c is emitted, the window plate 3a is cooled by flowing cooling water from the cooling device 7 into the fluid passage 6. Therefore, it does not reach high temperatures and does not emit light that causes unnecessary noise. In this way, highly accurate light can be emitted.
以上に説明したように、本考案にれば、アパー
チヤの周辺より不要な光が出なくなるので、検査
用の光（赤外線）として精度のよい光を発するよ
うになる。
As explained above, according to the present invention, unnecessary light is not emitted from the periphery of the aperture, so that highly accurate light for inspection (infrared rays) can be emitted.
