    • An infrared detector includes an outer cylinder having an infrared permeable window and an inner cylinder accommodated in the outer cylinder. The inner cylinder has an end surface, a cylindrical side surface, and an annular tapering surface formed between the end surface and the cylindrical side surface. The annular tapering surface has a diameter continuously decreasing toward the end surface. A multiple element type infrared sensor is mounted on the end surface of the inner cylinder, the infrared sensor having a plurality of output electrodes. A cryogenic cooling arrangement is provided for cooling the infrared sensor to low temperatures, and a signal fetching arrangement is provided for carrying a signal detected by the infrared sensor, the signal fetching arrangement including wiring patterns formed on the end surface, the tapering surface and the cylindrical side surface of the inner cylinder. The tapering surface of the inner cylinder is mirror-finished, and the wiring patterns are formed by laser-cutting a gold thin film deposited on the inner cylinder.
    • 红外检测器包括具有红外透过窗口的外筒和容纳在外筒中的内筒。 内筒具有端面,圆筒形侧面和形成在端面与圆筒形侧面之间的环状锥形面。 环形锥形表面的直径朝着端面连续减小。 多内容型红外线传感器安装在内筒的端面上,红外线传感器具有多个输出电极。 提供了一种用于将红外传感器冷却到低温的低温冷却装置,并且提供了用于承载由红外传感器检测到的信号的信号取出装置,该信号取出装置包括形成在端面,锥形表面和 内筒的圆柱形侧面。 内筒的锥形表面被镜面加工,并且通过激光切割沉积在内筒上的金薄膜来形成布线图案。
