Gentec-EO Ultrafast Joulemeter

02 M6 Detector

Measure every pulse at up to 200 kHz with MACH 6. Measure with 12-bit digital accuracy and capture up to 4 million pulses in real time. The Gentec-EO MACH 6 Joulemeter is the only instrument in the world that performs at this speed, and with this precision. It is designed to support the full complement of Gentec-EO fast energy probes that include Silicon, InGaAs and Pyroelectric Detectors. Measure from pJ to mJ and from 0.35 to 2.5 µm. Using the M6-Si detector and the M5-UC-QED accessory, you can make relative measurements at 266 nm. Read more.
