Ice Bloc TC is a high-power, precision temperature controller - available with a choice of 1 to 4 independent channels - for performing closed loop control with a temperature sensor and thermoelectric cooler/resistive heater to maintain and set the temperature of laser diodes, reference cavities, non-linear crystals, gratings and other temperature sensitive photonic devices.

Capable of controlling up to four TECs or heaters with set points in the range -70˚C to - 200˚C with a set point resolution of 1mK, Ice Bloc TC is optimised for T25 values from 10kΩ - 100kΩ but can be configured with a wider range.

Control and monitor devices and performance, via a standard Web/LAN connection and web browser. This can be network interlocked to any other Ice Bloc.
