The
Photothermal Common-path Interferometry (PCI)
Endurance Test evaluates material absorptance changes under custom laser irradiation over time. You can select up to five sites with chosen irradiation levels, each including additional L- and T-Scans (when applicable) for enhanced precision. Using, a low-power probe beam detects heating from an absorbed pump beam, measuring phase shifts to assess low absorption. This test provides insights into material degradation and endurance, useful for laser damage threshold and long-term performance evaluations.
