Ruby luminescence method pressure calculator*

Define the ambient temperature (in K): .
Enter the wavelength of the R1 emission line (in nm), measured at ambient pressure and ambient temperature: .

Enter the wavelength of the [shifted] R1 emission line (in nm), measured under pressure: .
What temperature was this wavelength measured at (in K)?: .

Click this button to calculate the pressure: .


The pressure (in GPa) using a linear p-v fit is: .
The pressure (in GPa) using the p-v equation suggested by Mao, Bell, and Steinberg is: .

*note: this calculator uses the (T, p, λ) = ( , ambient , ) 3-tuple defined by the user as the calibration "point" in temperature-pressure parameter space. v is the reciprocal wavelength.
