Device and system for detecting emissive ability of infrared emitter

The utility model discloses a device and a system for detecting emissive ability of an infrared emitter. The device comprises an infrared receiver for receiving an infrared ray signal and a homogeneous medium arranged at the front part of a light sensing area of an infrared reception diode, wherein the infrared receiver comprises the infrared reception diode and an amplification circuit. With adoption of the device and the system for detecting the emissive ability of the infrared emitter, an infrared reception device is not required to be placed in a farther position away from the infrared emitter, whether the emissive ability of an infrared emitter meets the preset requirement can be detected, smaller space is occupied, and the testing is more convenient.
