Light source assembly for detection of luminescence immunoassay analyzer

Abstract

The invention provides a light source assembly for detection of a luminescence immunoassay analyzer, the light source assembly comprises a housing body, a constant light source, an attenuation sheet and a dense light connecting piece, wherein the housing body is internally provided with a light propagation channel, the dense light connecting piece is provided with a light emission port. The constant light source, the attenuation sheet and the light emitting port are sequentially arranged along the light conduction direction of the constant light source; and the dense light connecting piece can be connected with a luminescence immunoassay analyzer to be calibrated. A weak constant light source which can be repeatedly used can be obtained by attenuating the constant light source, so that different numbers of photons generated by the luminous agent due to different batches of the luminous agent, different manufacturers, different use environments and different operators are avoided; the situation that the luminescence agent is harsh in preservation condition and inconvenient to use at clients; and the luminescence agent is high in cost is avoided.

Description

technical field [0001] The invention belongs to the technical field of detection equipment of a luminescence immunoassay analyzer, and in particular relates to a light source component for detection of a luminescence immunity analyzer. Background technique [0002] At present, manufacturers or R & D of luminescent immunoassay analyzers use the luminescent agent method to calibrate and judge the analyzer. The working principle is to use the luminescent agent as a light source, and the luminescent immunoassay analyzer reads the number of photons. Due to different batches of luminescent agents, different manufacturers, different use environments, and different operators, the number of photons produced by the luminescent agent is different, and the difference in the number of photons generated directly affects the calibration and judgment of the luminescence analyzer; the storage conditions of the luminescent agent are also very harsh. It is not convenient to use at the customer...

AI Technical Summary

Problems solved by technology

[0003] Therefore, the technical problem to be solved by the present invention is to provide a light source assembly for detection of a luminescence immunoassay analyzer, which can obtain a weak and constant light source for repeated use after attenuation by using a constant light source, so as to avoid different batches of luminescent agents, different manufacturers, and different use environments 1. The number of photons produced by the luminescent agent is different due to different operators, the storage conditions of the luminescent agent are harsh, it is not convenient to use at the customer's place, and the cost of the luminescent agent is high.
