A HANDHELD MINIATURE ULTRAVIOLET LED FLUORESCENCE DETECTION SPECTROMETER
Abstract
This paper presents a handheld micro-fluorescence spectrometer with an integrated ultraviolet light-emitting diode. A small transmission grating was used as a dispersive element to disperse light. The spectrum was detected by a CCD array. The instrument can be connected to a PC or a smartphone through a USB cable for data processing and spectrum display. The spectrometer is 30×30×100 mm3 only. The spectrometer with a wavelength range from 380 to 750 nm had a spectral resolution of 3 nm. The fluorescence spectra from edible oil, chlorophyll, and paper were measured by the spectrometer we designed. This spectrometer has the advantages of compact structure, small size, light weight, fast detection speed, convenient use, and low cost.
