Energy detector probe
Overview
SLT (Germany) Series PEM Standard broadband pyroelectric energy detectors with black absorption coating, nearly constant absorption from 185nm to 25µm; high sensitivity for µJ-level pulse energy measurement, direct connection to 1MΩ oscilloscope input via BNC, up to 500Hz repetition rate with PEM 710, 5 apertures (4-34mm).Description
【Overview】
Series PEM Standard pyroelectric energy detectors, manufactured by SLT Sensor- und Lasertechnik GmbH (Germany), feature a black absorption coating with nearly constant absorption (97±1%) from 185nm to 25µm. High sensitivity and immunity to interference allow µJ-level laser pulse measurement without an additional amplifier.
【Key Features】
(1) Black absorption coating, 185nm-25µm nearly constant absorption;
(2) µJ-level high sensitivity, interference immune;
(3) BNC direct connection to 1MΩ oscilloscope input;
(4) 5 active diameters (4/8/11/21/34mm);
(5) Up to 500Hz repetition rate with PEM 710;
(6) Optional 100kΩ load resistor for higher rep rates.
【Typical Applications】
Laser pulse energy measurement, laser adjustment and stability monitoring, research and industrial laser testing.
