The LDTC LAB series of instruments integrate precision temperature control and low-noise laser current output. The temperature controller half is compatible with a variety of temperature sensors, including thermistors, RTDs, linear current, and linear voltage sensors. The laser driver half is compatible with all laser diode and photodiode pin configurations.


Two models are available, the LD2TC5 LAB and the LD5TC10 LAB. The LD2TC5 LAB outputs up to 2 and 5 A for the laser and thermoelectric, respectively. The LD5TC10 LAB outputs up to 5 and 10 A. Both models offer 10 V of laser compliance voltage and 15 V of thermoelectric compliance voltage.


The instrument comes with a variety of powerful safety features to protect your equipment:

  • Adjustable current limit, with Brick-Wall Never-Exceed circuitry
  • Load failure protection
  • Temperature limits on the load
  • Current/voltage limits for both TEC and laser
  • Automatic laser shutdown upon TEC error available

With Wavelength’s plug and play instrument, you have the ability to quickly set the controls using either the instrument touch screen or a remote computer, and results are easy to monitor. This allows you to take your application from the test bench to market quickly and efficiently.


Wavelength’s proprietary IntelliTune algorithm characterizes the TE/sensor system’s response to the controller and determines the optimal PID control coefficients. It then automatically adjusts the PID control values as setpoint, tuning mode, or bias current change.

Run IntelliTune easily just off ambient and watch it change PID settings for a much higher or lower setpoint. After a single scan, explore either optimized Setpoint Response or Disturbance Rejection performance with your load to see which works best. Add or remove the D term to see if noise is an issue. IntelliTune lets you skip the manual characterization and it’s smart enough to really work—very little adjustment is needed after you have stored a successful characterization scan.


An Interlock Kit containing a BNC terminator for the laser interlock and a pre-soldered DSUB to satisfy the laser interlocks is included with the instrument. Loose connectors for custom cable configuration (CKL-103, CKT-202, and CKT-204) are shipped with the unit. Full cables for both the laser connection and the thermoelectric connection are available.


The LDTC LAB series of instruments are designed for electro-optical, medical, spectroscopic, and defense research where low-noise laser current is needed along with precision temperature control.
