This repository provides hardware schematics and list of materials for the open spectrometer project to enable practitioners, students and citizen scientists to collect data with their spectrometer and have a g.
Calibrating wavelength-dependent speckle patterns enables a multimode optical fiber to function as a spectrometer that is compact, lightweight, low cost, and provides high resolution with low loss. 03 nm resolution at wavelength 1500 nm. We demonstrate a design of an MMF spectrometer with scalable bandwidth using space-division multiplexing.
