Claims

[Scope of Claim for Utility Model Registration] (1) A photodetector unit that generates an electrical signal proportional to the intensity of incident infrared rays, a package that houses this photodetector unit, and a package that blocks incoming infrared rays from high-temperature surrounding components. A semi-cold shield with an effect,
In an infrared detector consisting of an inner all, an outer all, an infrared transmitting window, a deyuwa joint, and a cooler low temperature section, the junction between the semi-cold shield and the inner all is connected to the lowest temperature part of the inner all and the environmental temperature part. An infrared detector characterized by being detected in an intermediate temperature region. (2) A photodetector that generates an electrical signal proportional to the intensity of incident infrared rays, a package that houses this photodetector, a semi-cold shield that blocks infrared rays that enter from high-temperature surrounding components, and an inner In an infrared detector consisting of a wall, an outer all, an infrared transmitting window, a deyuwa joint part, and a cooler low-temperature section, the semi-cold shield and the inner all are joined at the hinge part provided on the outer periphery of the inner all. An infrared detector characterized by:
