Pyroelectric Pulse Energy Detectors
MKS/NewportRequest Info
The 919E Series detectors use innovative, patented technology which facilitates accurate and repeatable laser measurements of pulses over an extensive range of laser pulses. They can measure pulse sources with up to 25 kHz repetition rate. High pulse models can take up to 30 J pulse energy, while the photodiode based mode 919E-20U-10-20K can measure as low as 1 nJ. Every pulse energy up to 5 kHz can be logged with the 1919-R meter.
