500µJ-1J, 200 Hz, 50mm Energy Sensor with MaxUV coating and Diffuser for 248nm (RoHS)

The Excimer Laser EnergyMax Series comprises four different models, two that are optimized for operation at 193 nm and two that are intended for 248 nm (although all models are capable of producing accurate measurements throughout the UV, visible and near IR).  These sensors utilize our new MaxUV coating, which delivers high damage threshold at deep UV wavelengths, as well as excellent resistance to long-term UV exposure, and enables operation at repetition rates of up to 400 Hz.    

Excimer Laser EnergyMax Series products are also “smart” sensors, and incorporate onboard electronics to automatically correct for ambient temperature, as well as built-in wavelength compensation factors.  These sensors are compatible with Coherent LabMax-TOP, FieldMaxII-TOP, FieldMaxII-P meters.  

All Excimer sensors accept an optional heatsink, which can be easily attached by the user to extend the maximum energy or average power range.  Specifically, these heat sinks allow the J-25MUV-193 & -248 sensors to be used up to 18 W average power, and the J-50MUV-193 & -248 sensors to be used up to 43 W average power (both at 193 nm).
