The Optiprexx PLS is a stand-alone turnkey system that performs ruby photoluminescence measurements enabling the determination of the in-situ pressure in diamond anvil cells. The system includes a blue laser (450 nm @ 50 mW), spectrometer, transfer optics, optical observation stage, XYZ positioning stage and advanced data acquisition software. This system is recommended when measuring pressure above 50 GPa, to maximize the excitation of the Ruby and to optimize the fluorescence signal.

The Optiprexx PLS is extremely easy to use and is very compact, with the smallest possible footprint. The system connects to a computer (not supplied) equipped with an USB port to carry out the measurements.

The system includes our advanced control and acquisition software the Optiprexx High Pressure Manager.  This is a Python language based software designed by Almax easyLab that allows full spectrometer control, data acquisition and automatic or manual pressure determination.

A video tutorial demonstration of which is available on Almax easyLab’s YouTube channel.

Applications

The Optiprexx PLS 450 is used for ruby fluorescence manometry in diamond anvil cells. The system can provide an accuracy of +- 0.1 GPa or better on ruby fluorescence pressure determination.
