Overview
The 7244-08-28 Laser MultiSource has a 28V output for driving arrays of diodes while also having 8A for lower voltage, higher current lasers. Each output provides a fully indepenent, isolated output with individual analog modulation control.

At-a-Glance
  • 8A / 28V output
  • 2U Rackmountable
  • Ethernet and USB
  • 4 channels

Standard Computer Interfaces
The MultiSource includes both Ethernet and USB computer interfaces, allowing for quick and easy connection to a PC for remote operation. In addition, the command set is compatible with other Arroyo Instruments controllers, as well as those from ILX and Newport, allowing you to leverage any existing software you may have already developed.

Simple Local Control
While intended to be primarily operated from a PC, the display on the MultiSource allows you to locally monitor status and turn channels on and off.
