Laser diode controller with precision temperature controller

6300 Series ComboSource

Arroyo Instruments Logo

The 6300 Series ComboSource Laser Diode Controller offers the best of both worlds: a high accuracy, low noise, dual-range laser driver combined with a powerful 60W precision temperature controller.

The ComboSource laser driver includes the standard safety suite: a safety interlock, ESD protection, and hardware limit circuits for current and voltage. Dual range allows this instrument to operate at half-scale for improved resolution.

In addition, the ComboSource has unique features not found on competing products including optically isolated modulation and photodiode inputs, programmable PD bias, and a constant voltage control mode.

The ComboSource temperature controller supplies 60 W of TEC control and supports all common sensor types (thermistor, RTD, AD590, and LM335), including a 4-wire RTD mode. With the same excellent stability and performance as our popular 5305 TECSource, the ComboSource supports a broad range of laser and temperature control applications.

  • Laser: Standard compliance voltages up to 10V
  • Laser: High accuracy, stability, and low noise
  • TEC: AutoTune for automatic PID calculation
  • TEC: Fully adjustable PID settings
  • TEC: Simultaneous display of temperature set point, actual temperature, current, and voltage
  • Large, clear VFD display easily viewable with laser goggles
  • Advanced laser diode protection
  • USB / RS-232 computer interfaces
  • Command set compatibility with Newport and ILX controllers
