Fluorescence detection device

Abstract

The invention discloses a fluorescence detection device, which comprises a laser light source device, a radiator device and an incident fluorescence detection device. The laser light source device communicates with the bottom of the sample tube on the upper surface of the radiator device through an exciting optical fiber, and the receiving optical fibers converge into a bundle. It is connected with the incident fluorescence detection device, and the incident fluorescence detection device is connected with a single-chip microcomputer to read and process the signal. The technical solution of the present invention is not only simple and practical, but also convenient for subsequent engineering, batch production, and clear process introduction; two optical fibers reach the bottom of the sample, The signal is strong, which saves the problem of weak optical signal in other solutions; and the optical path between the optical fiber and the sample can be adjusted freely to achieve free adjustment of light intensity, which solves the problem of light inhomogeneity in traditional solutions.

Description

technical field [0001] The invention relates to the technical field of optical detection, in particular to a fluorescence detection device. Background technique [0002] At present, many fluorescence detection devices on the market use a diphasic color lens to form a certain angle between the detection sample, the excitation light source and the fluorescence receiving device. This solution not only has high cost, but also has disadvantages such as weak signal (long optical path) and edge effects. , based on the above considerations, the fluorescence detection device was invented. [0003] One of the existing fluorescent detection devices adopts the structure of the top laser, and its defect is that the signal is relatively weak. The second is the structure of using the side laser. Since the optical fibers are all drawn out from the side, it takes up a lot of space and cannot achieve large-scale detection. Quantity is detected at the same time, and the processing is difficul...
