Fluorescence Wavelength Pressure Calculator
Written by James Badro

This Java applet calculates the pressure according to the shift of calibrated fluorescence lines.

Only Al₂O₃:Cr³⁺ (Ruby !) and SrB₄O₇:Sm²⁺ are supported.

This program uses exact integral equations for the temperature dependance of the ruby fluorescence line. It is valid for all temperatures, but heavy on calculations. For low temperature measurements (T<400 K), use the other applet.

The hydrostatic (7.665 power law) and non-hydrostatic (5.0 power law) ruby scales are both implemented.

This script is based on a FORTRAN program by Florent Occelli.

The pressure dependance of the ruby scale is from Mao et al.

The pressure dependance of the SrB₄O₇:Sm²⁺ scale is from Loubeyre et al.
