Embodiment 1
[0030] Please refer to figure 1 with figure 2 The fluorescence detector of this embodiment includes a fluorescence collector 01 for collecting fluorescence, which is made of multiple optical fibers. The fluorescence collector 01 includes a collection end 011 and a detection end 012. The collection end 011 of the fluorescence collector 01 It is tapered to the detection end 012, so that the cross-sectional area of the collection end 011 is larger than the cross-sectional area of the detection end. The collection end 011 is used to collect fluorescence signals at large angles and in a wide range. When the fluorescence irradiates the cross-sectional area of the collection end 011 The collected fluorescence signal is gathered to the detection end 012 when it is transmitted in the fluorescence detector, so that the fluorescence signal follows the principle of full emission when transmitted in the optical fiber, so there is no loss during transmission, high transmittance and f...
Embodiment 2
[0039] This embodiment provides a fluorescence detection array, which includes a plurality of fluorescence detectors as provided in Embodiment 1, and the plurality of fluorescence detectors are closely and neatly arranged, so that the collection ends of the fluorescence collectors of the plurality of fluorescence detectors are on the same plane and the sides of two adjacent fluorescence collectors are in close contact, so that fluorescence signals in a wide angle and a wide range can be detected, and fluorescence signals in various wavelength ranges can be collected, which has the advantages of high collection accuracy and wide coverage .
[0040] Among them, the filter wavelength ranges of the filters set on the detection ends of the fluorescence collectors of the multiple fluorescence detectors are different, so that the fluorescence of different wavelength ranges can be collected, which can not only increase the light intensity of each light wave, but also reduce the size of...
Embodiment 3
[0043] This embodiment provides a fluorescent detection array, such as Figure 4-6 , which includes six fluorescence detectors as provided in Embodiment 1, and the fluorescence collectors of the six fluorescence detectors are as follows image 3 The labels in 01, 02, 03, 04, 05 and 06 correspond to the six fluorescent detectors arranged closely so that the collection ends of the fluorescent collectors of the six fluorescent detectors are on the same plane, and the six fluorescent detectors The detectors are arranged in two rows, three in each row, and the sides of two adjacent fluorescence collectors are in close contact. The filters on the detection ends of the six fluorescence collectors respectively select filters with wavelength ranges of 430±30nm, 490±30nm, 550±30nm, 610±30nm, 670±30nm and 730±30nm, so that the collected Fluorescence over a wide range of wavelengths. Such as Figure 5 with Image 6 Among them, the filters labeled 11, 12, 13, 14, 15, and 16 have wavele...
