Pulse energy monitors of EM series allows conveniently measure pulse energy of our lasers. Detector can be attached to any component that has internal SM05 thread. Photodetector cable with BNC plug should be connected to the laser controller.
Monitor consist from beam splitter that splits approx 2% from total pulse energy, and photodetector. Colored and/or neutral density filters are used to cut unwanted wavelengths and calibrate photodetector readings.
Measured pulse energy can be presented to the user in digital or analog form. Analog DC voltage, proportional to the last pulse energy is provided from BNC socket on the rear panel of laser controller. Digital value can be retrieved trough laser Ethernet interface.
Each monitor is factory calibrated at specified wavelength. Broadband version is available, in this case calibration is performed at 1053 or 1064 nm wavelength.
