ULTRA-STABLE TEMPERATURE CONTROLLER & LOW-NOISE LASER DRIVER
The LDTC LAB Series instruments combine best-in-class low noise, high-end digital control laser diode driver technology with an IntelliTune® smart temperature controller. If you need stable wavelength, stable temperature (better than 0.0009ºC with thermistors), stable laser diode current or power, or low noise (RMS laser driver noise as low as 7 µA), these offer the best performance and value.
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 touch-screen interface makes operation intuitive and simple. A LabVIEW® virtual instrument, remote command set, and USB interface allow integration into an instrument library.
Operation in Constant Current (CC) or Constant Power (CP) mode changes with the touch of a button. A wide variety of sensors work in the temperature control feedback loop.
PROTECT YOUR THERMOELECTRIC AND LASER
Safety features protect the thermoelectric cooler (TEC) and the laser. Positive and negative (where applicable) current limits with Brick-Wall Never-Exceed circuitry can be set. If the sensor signal is lost or a short is detected at the TEC, output current is disabled. Passive and active interlocks are available for safety of equipment and user. You can link laser diode current to safe and stable thermoelectric operation. The instrument comes with a variety of other powerful safety features to protect your equipment:
- Load failure protection
- Over- and under-Temperature limits on the load
- Current/voltage limits for both TEC and laser
- Automatic laser shutdown upon TEC error available
INTUITIVE USER INTERFACE AND SUPERIOR SOFTWARE CONTROL
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.
IntelliTune®: INTELLIGENT AUTOTUNE
Wavelength’s proprietary IntelliTune algorithm characterizes the TEC/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. See Application Note AN-TC13: IntelliTune® vs. Conventional Autotune for an in-depth exploration.
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 LDMOUNT-5A, a 14-pin butterfly laser diode mount with integrated heat sinking, is available for simple connections between the LDTC and the laser.
The ultra-stable temperature controller/laser driver instruments are particularly reliable for diverse fields such as medical, defense, communications and manufacturing. Applications include particle and droplet measurement, communications, manufacturing test, and medical systems. Additionally, our products are designed for use with electro-optical systems, airborne instrumentation, spectroscopic monitors, and medical diagnostic equipment.
Free, effective, and responsive technical support is available to simplify integration of Wavelength products into your OEM design. The standard product can be easily modified to meet your application requirements.
