USB-enabled Energy Sensor, 2.4mJ-3J, MaxBlack Coating and Diffuser for Nd:YAG

Manufacturer's part number :


Manufacturer Coherent


Description :

EnergyMax-USB J-50MB-YAG Energy Sensor allow measurements over a wide range of wavelengths, beam diameters, average power levels, and repetition rates. The MaxBlack coating on this sensor provides significant damage resistance and mechanical durability characteristics compared to the black paint coatings often used on broadband sensors in the past.
