Coherent J-25MUV-248 Pulse Energy Sensor Description：

Datasheet

This J-25MUV-248 energy sensor incorporates the MaxUV coating and is optimized for use with ArF lasers operating at 193 nm and KrF lasers at 248 nm. This sensor is directly calibrated at 248 nm and includes spectral compensation from 193 nm to 2.1 µm. It is terminated in a SmartProbe DB25 cable and is directly compatible with FieldMaxII-TOP, FieldMaxII-P, LabMax-TOP, and LabMax-Pro SSIM meters.

A small heatsink (PN 1123430) and medium heatsink (PN 1123431) is available to extend the energy and repetition rates of EnergyMax sensors by increasing the average power capability.

Pyroelectric energy sensor with MaxUV coating for measuring laser pulses from 125 µJ to 250 mJ at up to 500 pps.
