Additional Notes
Source document: Leica Microsystems Technical Report SA-223726_V1.pdf. Reported asset details: Equipment STELLARIS FALCON - 13334341, serial number 8300000681, product 158305100, product family X01. The report lists operations CALL4 and TRVL4, signed by Alexander Ponomarev on 2025-12-23 06:23. The report does not provide measured laser powers, so this maintenance event records the vendor statement only and does not create structured laser-power QC values. No specific follow-up action was stated in the service report; continue routine laser/QC monitoring and record measured WLL line powers in a QC session if local measurements are performed.
