Measure excimer laser energy with more
precision
Excimer laser EnergyMax series sensors feature high accuracy and large active area, and utilise a novel coating that delivers superior long-term damage resistance
A new range of pulse energy sensors from Coherent are specifically optimised for use with ArF lasers operating at 193nm and with KrF lasers at 248nm They can perform pulse energy measurements from 50uJ to 250mJ, and operate at repetition rates from single shot to 400Hz

Violet laser producing power from 4mW to 30mW at 408nm for series a range of applications including cytometry, high-throughput screening, and confocal microscopy
These sensors are compatible with Coherent 3sigma, FieldMaxII-top, FieldMaxII-P, EPM1000 and EPM2000 meters.
The Excimer Laser EnergyMax series comprises four individual products.
These are 25mm and 50mm diameter sensors calibrated specifically at either 193nm or 248nm.
Onboard sensors provide automatic temperature compensation, and built-in spectral compensation enables quantitative operation at other wavelengths, as well.
Both 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 25mm Excimer Laser sensor to be used up to 18W average power, and 50mm sensors to be used up to 43W average power (both at 193nm).
