6300 SERIES FEATURES

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, coming together as our flagship product.

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 60W 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.

DUAL RANGE LASER DRIVER

Operates at half-scale for improved resolution and lower noise.

OVERLAPPING LASER PROTECTION

Including safety interlock, ESD protection, hardware limits for current & voltage, soft power-on, and intermittent contact safeguards.

MULTIPLE OPERATING MODES

Choose from:

  • Constant Current
  • Constant Power
  • Constant Voltage

REMOTE VOLTAGE SENSING

Supports an extra pair of sensing wires to measure the operating voltage of your laser diode or LED.

AUTO-TUNE AND MANUAL PID SELECTION

One button auto-tunes your control loop, or choose from 8 factory gain settings, or select your own.

POWERFUL TEMPERATURE CONTROLLER

Supplies up to 60 Watts of TEC control and up to ± 0.004 ºC. Works with a thermistor, LM-335, AD-590, or an RTD.
