High-precision spatial mapping control for a glove box-integrated Raman spectrometer

Abstract

An electronic control system developed by our team for spatial mapping in Raman spectroscopy integrated with a glove box is described in this article. Key features include a Positioning and Optical Preview System with a 3-axis NanoMax stage for precise sample mapping, a Control Module based on the STM32F207 microcontroller for managing stage movements and synchronisation, and a custom software solution enabling measurement synchronisation via TTL signals. To validate our Raman mapping methodology, we analysed mechanically ground α-MoO₃ powder deposited on glass. The acquired spectra clearly exhibited all the characteristic vibrational modes of the orthorhombic phase, confirming the reliability of our mapping technique.
