  • Direct USB interface
  • ISO 17025 accredited

The J-50MB-YAG-1528 energy sensor is a higher repetition rate model than the standard J-50MB-YAG. This 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-USB J-50MB-YAG-1528 energy sensor is terminated in a USB cable that interfaces directly to a PC. A DB25 model (PN 1144701) 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.
