The J-50MB-IR energy sensor is specifically design for high energy and high peak power Erbium and Holmium medical lasers. This sensor is like the J-50MB-YAG, but is designed to operate further in the infrared.

The EnergyMax-USB J-50MB-IR energy sensor is terminated in a USB cable that interfaces directly to a PC. A DB25 model (PN 1155722) is available.

A large heatsink (PN 1123432) is available to extend the energy and repetition rates of EnergyMax sensors by increasing the average power capability.
