Thorlabs Profile LD /TE 8052 ITC Controller Module QTY 1

The Thorlabs ITC8052 is a dual-channel controller module for laser diode and thermoelectric cooler (TEC) management within the PRO8000 series chassis. It delivers independent current and temperature regulation in a single-slot format, supporting both constant current and constant power modes for laser diodes while maintaining TEC stability below 0.001 °C. Built-in protection and flexible sensor compatibility make this module suitable for precision telecom and industrial laser applications requiring long-term reliability.
