Résumé
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 prototype (battery powered; module + measurement head weight: <1.6 kg) is controlled via a military-grade smartphone and has a limit of detection for chlorophyll better than 5 ng/cm
