A Compact LIF Spectrometer for in-Field Operation in Polar Environments
We present a compact laser-induced fluorescence (LIF) spectrometer prototype (SFIDA–405) designed for in-field operation in polar environments. It uses 405 nm excitation to acquire LIF spectra in the 450–930 nm spectral range on a solid surface via an optical-fiber coupled measurement head. The prot...
