Laser high energy probe
Overview
SLT (Germany) Series PEM K energy detectors with ceramic coating for highest energy densities: high damage threshold, short time constant, high sensitivity and large aperture; cleanable with most solvents or disinfectants, ideal for medical applications and Excimer/CO2-TEA/Nd:YAG lasers.Description
【Overview】
Series PEM K detectors use a highly resistant ceramic coating for pulse lasers with high power density (Excimer, CO2-TEA, Nd:YAG), offering high damage threshold, short time constant, high sensitivity and large aperture. The surface can be cleaned with most solvents or disinfectants, ideal for medical applications.
【Key Features】
(1) Ceramic coating for highest energy densities;
(2) Cleanable surface (most solvents/disinfectants);
(3) High damage threshold for Excimer lasers, ideal for medical use;
(4) 1064nm permissible peak power density 120 MW/cm², energy density 970 mJ/cm²;
(5) PEM 45 K USB with integrated USB output, working range 1mJ-1J.
【Typical Applications】
Excimer (308nm), Nd:YAG harmonics (355/532/1064nm), CO2-TEA laser energy measurement, medical laser testing.
