Abstract
The invention discloses a fluorescence detector and relates to the optical-mechanical field. The fluorescence detector comprises a housing and internal components. The internal components contain a fluorescence excitation light-path, a fluorescence receiving light-path and a signal processing system. The housing is provided with a power switch and a receive switch. The housing is equipped with a photoscope which brings convenience for eye detection during instrument detection. The side of the photoscope, close to the internal components, is provided with a silver iodide coating which changes colors when encountering ultraviolet light so as to resist ultraviolet light and protect eyes. The fluorescence excitation light-path contains an excitation light source, an interference filter and a sample cell. The interference filter is detachable. When the interference filter is mounted, ultraviolet transition can happen, and fluorescent light is produced by excitation. When the interference filter is dismounted, the fluorescence excitation light-path can be used as an ultraviolet-visible detector. The receive switch can independently control the signal processing system. When fluorescent light cannot be seen by naked eye, there is no need to rerun the signal processing system. Thus, system operation load is reduced, and service life is prolonged.
