Wide-temperature weak light detector

The utility model relates to a wide-temperature weak light detector, which comprises a chip, a carrier, a metalized optical fiber assembly and a shielding cover, the chip is arranged on the carrier, and the shielding cover, the carrier and the metalized optical fiber assembly jointly form a shielding cavity to protect the chip in the shielding cavity. The shielding cavity is arranged in the chip to shield interference of background light noise on the chip, and one end of the metalized optical fiber assembly is close to the chip and located in the shielding cavity. According to the utility model, noise photons radiated by high-temperature elements such as a tube shell are effectively shielded through the shielding cover, so that the performance of the device at high temperature can be effectively improved. In addition, the possibility that noise light enters the chip can be further reduced through the shielding effect of the metal area on the surface of the chip. 本实用新型涉及一种宽温微弱光探测器，包括芯片、载体、金属化光纤组件以及屏蔽罩，所述芯片设置在所
