Coherent EnergyMax sensors enable laser pulse energy measurement over a broader range of wavelengths, repetition rates, pulse energies and beam diameters than any other product available.  With their unique combination of superior performance and user friendly convenience, an EnergyMax sensor is your best choice no matter what your particular laser energy measurement need.

EnergyMax Performance Advantages

• Superior damage resistence
• High repetition rate operation
• Large dynamic range gives each sensor broad coverage
• Low noise and excellent linearity for greater accuracy
• Large active area

EnergyMax Convenience Features

• High accuracy, spectral compensation characteristics built into each unit
• Onboard sensors provide automatic temperature compensation
• Modular heat sinks to extend measurement range
• Compact size to enable measurements within instruments
• Molded cable with bend and strain relief protects against rough handling

Coherent offers four different series of EnergyMax sensors to satisfy a diverse range of measurement requirements. These are:

• Multipurpose: sensors for a wide variety of uses -- ideal for general laboratory usage
• High Repetition Rate: for up to 10 kHz operation
• YAG/Harmonics and IR: specifically for Nd:YAG, Ruby and Holmium lasers
• Excimer Laser: intended for 193 nm and 248 nm excimer lasers
• New! Quantum EnergyMax Sensors

EnergyMax sensors are compatible with Coherent 3sigma, FieldMaxII-TOP, FieldMaxII-P, EPM1000 and EPM2000 meters. (Note: High Repetition Rate sensors are the only EnergyMax series sensors not compatible with FieldMaxII due to the high repetition rate.)

The table below provides the primary specifications for each of our laser energy sensors, and can be sorted by any of those parameters. You can select two or more sensors for quick comparisons between various models.
