Price $2,970.00


Pyroelectric energy sensor with MaxBlack coating and diffuser for measuring laser pulses from 12 mJ to 15J at up to 10 pps. Direct RS interface.

 Key Features:

  • 0.266 to 2.1 µm spectral range
  • 35 mm diameter active area
  • 12 mJ to 15J energy range
  • 10 pps repetition rate operation
  • Direct RS232 interface
  • ISO 17025 accredited

The J-50MB-YAG-1535 energy sensor can handle higher pulse energy and longer laser pulse lengths 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-RS J-50MB-YAG-1535 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 1151431) 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.
