The FieldMaxII™ laser power and energy meter from Coherent® functions with a broad range of EnergyMax™ sensors enabling laser pulse energy measurement over a broad range of wavelengths, repetition rates, pulse energies and beam diameters. EnergyMax™ sensors are highly linear in terms of repetition rate, laser pulse width, and measured energy. They are also accurate across a broad range of wavelengths due to onboard wavelength compensation. In addition, automatic temperature compensation accounts for changes in ambient temperature, as well as for heat generated by absorption of the laser energy. The included software provides an easy and convenient way to monitor and control multiple meters from a single computer as well as allows the user to log and manipulate measurement data. Complete system requires the FieldMaxII™ meter and an EnergyMax™ sensor.

In addition to EnergyMax™ sensors, the FieldMaxII™ is also compatible with all Coherent® High Power Laser Power Meter detector heads
