Hangzhou Torch Bearer Technology Co. Ltd, founded in 2017, is committed to the development of micro-spectrometer. Utilizing the novel nano organic-semiconductor materials, single-layer optics structure design, micro-nano fabrication technology for optical meta-surfaces, and the spectral inversion algorithm which is built on the artificial neural networks (TensorFlow), Torchbearer Tech achieves the miniaturization of spectrometer. The new type of micro-spectrometer with the compact modular design can be widely used in the fields of consumer electronics, AIOT, substance analysis, environmental protection, food safety and optics general use. Compared with the traditional spectrometer, it is in the leading position in the same type of products with smaller size, better spectral detection performance and higher cost performance.
