Spectral analyser of visible and near-visible radiation - uses light conductors, monochromators and individual receivers

摘要

A spectral device with several monochromatic receivers is used for measuring the spectral light intensity of electromagnetic radiation in the visible and neighbouring spectral regions (infra-red and ultra-violet). It enables analysis of materials transmitting or reflecting light, accurate colour measurement, and odour consistency monitoring of different objects. The light being analysed is gathered by a bundle of light conductors at each of whose outlet ends a monochromator is arranged with a partic. spectral transmission characteristic. The monochromators filter the partial light segments and pass them to individual receivers.
