【考案の詳細な説明】
本考案は赤外放射温度計に関するもので、被測
光部位を明示し、測光位置の安定化を図ることを
目的とする。[Detailed Description of the Invention] The present invention relates to an infrared radiation thermometer, and its purpose is to clearly indicate the area to be measured and to stabilize the photometric position.
従来この種の装置においては、測光位置を明確
にするものが無かつた。しかし類似のものとして
１本のビーム（光線）で位置を指定するものがあ
つたが、装置と測光場所の遠近が明確に把握でき
ない欠点があつた。 Conventionally, in this type of device, there was nothing that clarified the photometry position. However, there was a similar method that specified the position using a single beam (light ray), but it had the disadvantage that it was not possible to clearly determine the distance between the device and the photometering location.

１図において１は赤外線集光レンズで、物体２の

The infrared rays (indicated by diagonal lines in the figure) are focused on the element 4a of the detector 4.

り、離れすぎれば第２図イのようになる。 Next, an optical system having an optical axis 6 tilted by an angle θ with respect to the optical axis 5 of this lens 1 is provided. That is, 7 is a light source having a filament 8, 9 is a condenser lens, 10 is a minute aperture, and 11 is an imaging lens. A light beam from a light source 7 is focused onto an aperture 10 by a condenser lens 9. The light beam passing through the aperture 10 forms an image on the object 2 of a filament regulated by the diameter φ1 of the aperture 10 with a size corresponding to the diameter φ2 by the imaging lens 11. Two of the above lens systems are provided symmetrically around the lens 1 as shown in the figure, and when the light source 7 is attached, the filament images are orthogonal to each other.
The direction of the filament 8 of the light source 7 is determined and fixed as follows. By doing this, the filament images corresponding to the diameter of φ 2 regulated by the aperture 10 from the two lens systems are projected onto the position of the minute area portion 3 on the object 2 and intersect, as shown in FIG. In addition, the two filament images are orthogonal to each other and form a cross shape, making it possible to clearly grasp the center of the photometry position. If the photometry position is too close to the object 2, the filament image will look like the one shown in Figure 2C, and if it is too far away, the filament image will look like the one shown in Figure 2A.
なおφ２の径と微小面積部分３の径とを一致さ
せておけば一層便利である。こゝで、赤外線集光
レンズ１としては主にGe，Si，KRS等が使用さ
れる。 Note that it is more convenient if the diameter of φ2 and the diameter of the small area portion 3 are matched. Here, as the infrared condensing lens 1, Ge, Si, KRS, etc. are mainly used.
また上記実施例では光源７のフイラメント８に
よる像を物体２上に結像させるようにしたもので
あるが、他の光像であつてもよい。 Further, in the above embodiment, an image formed by the filament 8 of the light source 7 is formed on the object 2, but other light images may be used.

整し得る利点を有する。 As is clear from the above embodiments, according to the present invention, since visible light does not pass through, the same optical system is shared like in a general camera, and a reflector cannot be used to place a viewfinder, but an optical system is provided. This makes it possible to clearly define the temperature photometric point, which is particularly effective when used for medical purposes. In addition, in the above configuration, since the interval and shape between the light images formed by the two sets of light beams projected onto the object are observed, it is possible to not only adjust the distance between the object and the photometry device, but also to
This has the advantage that the inclination of the object with respect to the optical axis of the photometric device can also be adjusted.
