USB-enabled Energy Sensor, 850µJ-1J, 1kHz, MaxBlack Coating

Manufacturer's part number :


Manufacturer Coherent


Description :

EnergyMax-USB J-25MB-HE energy (meterless) sensor contain miniaturised meter electronics and an RS-232 interface that are integrated within the sensor cable. Additionally, stacking (of up to four) EnergyMax sensors enables all connected units to share both internal and external triggers for synchronized operation, for applications such as pulse-to-pulse (A/B) ratiometry.
