Handheld Spectrometer Wirelessly Transmits Data to Smartphone
HAIKOU, BEIJING and HANGZHOU, China, Nov. 17, 2017 — A wireless handheld spectrometer that is smartphone-compatible could make it easier and more economical to acquire spectral images of everyday objects and in the future could be used for point-of-care medical diagnosis in remote locations. The device can detect wavelengths from 400 to 676 nm and a white LED array lamp is used as the light source. The wavelength resolution of the spectrometer is about 17 nm. Rather than using a smartphone camera to acquire images, the new spectrometer uses
