Minimum Temperature Range of the LDM-4405

The LDM-4405 is designed to provide temperature control and convenient mounting for 5.6mm and 9mm TO-Can laser diodes with up to 4 pins. Temperature control is provided by an integrated thermoelectric module (TEC) with power ratings of 3.9A and 3.7V. A calibrated 10kΩ thermistor imbedded in the nickel plated cold plate is used for temperature feedback to a thermoelectric temperature controller. The heat generated by the TEC and laser diode is removed by a finned heat sink on the LDM-4405 through natural convection. The LDM-4405 temperature range is specified as 10°C to 85°C for heat loads up to 500mW.
