In order to narrow the viewing angle of the infrared rays incident on the sensing element forming the detector as much as possible and eliminate unnecessary background radiation other than the infrared rays emitted from the object to be detected, a layer of copper, for example, is usually placed around the sensing element. An aperture made of a metal member such as (Cu) is installed.

で冷却されている。The structure of such a conventional infrared detector, particularly near the aperture, will be explained using FIGS. 1 and 2. 1st
As shown in the figure, in a conventional infrared detector, an infrared detection element 1 is mounted on a zaphire substrate 2, and around it is formed of a thin metal member such as Co, and a box shaped like a rectangular parallelepiped is formed. Apertures 3/1 and 3B each having a rod-like shape formed by hollowing out the bottom of the board are installed on the board using screws 4 or the like. And this aperture 3A,
311 defines the viewing angle θ of the infrared sensing element 1. Although not shown, this zaphire group (lower part of anti-2) is installed on a cooling base made of tμJ (Cu), etc., and the cooling base is cooled with a refrigerant such as liquid nitrogen. .

であった。However, it is difficult to process apertures with such a conventional structure, and in particular, the distance h1 from the infrared sensing element 1 surface to the first aperture 3A and the distance 1+2 from the infrared sensing element surface 1 to the second aperture 3B are precisely and minutely dimensioned. Since it is difficult to process the infrared rays incident on the infrared detector, the spacing hl and h2 becomes large, and the optical system such as a condensing lens for condensing the infrared rays incident on the infrared detector becomes large, or the viewing angle θ becomes large. It was difficult to control ff1l to a desired value.

A frame-shaped aperture should be installed to surround the area.

θをｇｌ’ｉ１節できる。As shown in FIG. 3, in the infrared detector of the present invention,
A fiber plate 13 consisting of a core 11 and a cladding 12 is used instead of the metallic aperture used in conventional infrared detectors, and the core 11 of this fiber nibrate 13 faces the infrared sensing element 1 at a predetermined distance. For example, it is attached to the sapphire substrate 2 using a suitable gold-plated metal fitting. This fiber plate is made of 4 element (As)-sulfur (S) system, arsenic (As)-selenium (Se)-tellurium (Te system), germanium (Ge)-arsenic (As) system, which easily transmits infrared rays.
- It is formed using a tellurium (Te)-based chalcogenide glass, and the refractive index of the core 11 is higher than that of the crund 12. Furthermore, as the difference between the refractive index of the core II and the cladding increases, the angle of light incident on the center of the core of the fiber plate 13 from the outside, that is, the light receiving angle φ of the core increases, and the numerical aperture (N,
The large fiber plate 13 of A) is obtained. Therefore, by appropriately adjusting the refractive index difference between the core 11 and the cladding 12 of the fiber plate 13 to be formed, the viewing angle θ of the infrared light incident through the fiber plates 1 and 13 can be set to gl'i1.
