The Newport 9605 is an integrated laser diode driver (LDD) and thermoelectric cooler (TEC) controller module that delivers precise current regulation and thermal stabilization in a single compact unit. It combines low-noise laser current sourcing with ±0.1% accuracy and advanced TEC control capable of maintaining temperatures to ±0.007°C over one hour. Designed as a modular plug-in for Newport multi-channel controller mainframes, the 9605 addresses applications demanding stable optical output, wavelength precision, and tight temperature regulation in laboratory and production environments.
