The J-50MB-YAG energy sensor is specifically design for high energy and high peak power lasers operating at relatively low repetition rates, such as those based upon Nd:YAG, Ruby, Ho:YAG, and Erbium. The J-50MB-YAG can be used with beams up to 35mm in diameter and can work at 1064 nm, 532 nm, 355 nm, and 266 nm without the need to change diffusers or self-calibrate the sensor.

The EnergyMax-RS J-50MB-YAG energy sensor is terminated in an RS232 cable that interfaces directly to a PC or industrial controller. Power must be provided via a 5VDC power supply (optional PN 1105557) or via Pin 1. A DB25 model (PN 1110744) is available.
