Embodiment Construction
[0012] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0013] Such as figure 1 As shown, the monochromatic fluorescence detection device of the present invention is applied to a portable fluorescence immunoassay analyzer, and includes a photodetector 1, an aperture diaphragm 2, a focusing lens 3, a first filter 4, a dichromatic mirror 5, and a parabolic reflector Mirror 6, second filter 7, collimating lens 8 and LED light source 9.
[0014] Photodetector 1, pinhole diaphragm 2, focusing lens 3, and first optical filter 4 are aligned in order to form a receiving optical path; the dichromatic mirror 5 and the optical axis of the receiving optical path form a 45° angle on the horizontal plane, and an off-axis paraboloid The reflector 6 forms a certain angle with the optical axis of the receiving optical path on the vertical plane, and reflects the optical axis downward to ensure tha...
