title: Note: a portable, light-emitting diode-based ruby fluorescence spectrometer for high-pressure calibration.
abstract: Ruby (Al(2)O(3), with ∼0.5 wt. % Cr doping) is one of the most widely used manometers at the giga-Pascal scale. Traditionally, its fluorescence is excited with intense laser sources. Here, I present a simple, robust, and portable design that employs light-emitting diodes (LEDs) instead. This LED-based system is safer in comparison with laser-based ones.
