Light path system of multi-channel enzyme immunoassay microplate reader

Abstract

The invention relates to a multi-channel enzyme immunoassay microplate reader light path system, which comprises a light path system and a detection system, the light path system comprises an excitation light source, an optical fiber, a uniform light bar, a light beam amplification system, a plano-convex lens and a porous plate which are arranged in sequence, and a light beam emitted by the excitation light source is coupled by the optical fiber and then is emitted into the uniform light bar; after passing through the uniform light rod, the light beam is amplified by the light beam amplification system, the amplified light beam is emitted to the perforated plate after penetrating through the plano-convex lens, and the plane side of the plano-convex lens is arranged close to one side of the light beam amplification system; and the light beam enters the detection system through the solution on the porous plate. The multi-channel enzyme immunoassay microplate reader light path system provided by the invention is simple in structure, low in cost and high in detection efficiency.

Description

technical field [0001] The invention relates to an optical path system of a multi-channel enzyme immunoassay plate reader, belonging to the technical field of medical devices. Background technique [0002] At present, the light path of traditional microplate readers mostly uses halogen tungsten light source or LED light source, which is transmitted through optical fiber or directly projects a large spot. A high-power halogen lamp is used to excite the light, and then the beam is shunted and transmitted to the sample area through an optical fiber for irradiation, but this method requires high power of the light source, which requires a high-power light source to achieve, and the halogen lamp is used for a period of time Afterwards, the light intensity will attenuate, and it needs to be replaced regularly, which is troublesome, complicated in structure, and low in detection efficiency. Contents of the invention [0003] The technical problem to be solved by the present inve...
