Problems solved by technology

Although fluorescent sensors can be miniaturized, their detectors are more expensive
If you do not use a detector and observe directly with the naked eye, the sensitivity of the detection is low because the sensitivity of the human eye is not high

Abstract

The invention relates to a visual fluorescence sensor for ultraviolet detection and a manufacturing method of the visual fluorescence sensor, and belongs to the technical field of devices sensitive toultraviolet radiation. The fluorescence sensor comprises an imaging channel and functional elements, wherein the imaging channel is used for providing a conduction channel required by light from entering to imaging, and is also used for providing an arrangement basis for the functional elements; the functional elements comprise a filter element, a reflection element, a fluorescence excitation element, an imaging element and a superposition light source element. The fluorescent sensor is used for ultraviolet detection and has the advantages of being small in size, low in cost, simple to operate, visual and recyclable, and the manufacturing process is simple.

Description

technical field [0001] The invention relates to the technical field of devices sensitive to ultraviolet radiation, in particular to a visible fluorescence sensor for ultraviolet detection and a manufacturing method thereof. Background technique [0002] Ultraviolet detection sensor refers to a sensor that generates different photoelectric signals from semiconductor materials that respond to ultraviolet rays under different ultraviolet intensities. For example, the Chinese utility model patent with application number CN 201720018821.7 discloses a highly sensitive micro-integrated ultraviolet detection sensor. The sensor has a chip set on the circuit board connected with the electric signal, the chip set is connected to the circuit board through the chip set connection line, the package layer is arranged around the chip set, the chip set includes several ultraviolet detection chips, and the ultraviolet detection chip The ultraviolet detection sensor has the advantages of high ...
