The MKS Instruments/Newport 8000 Modular Controller is a four-bay mainframe engineered for independent control of laser diode drivers (LDD) and thermoelectric coolers (TEC). Each bay is fully isolated, accommodating plug-in 8630 LDD/TEC cards that deliver precision current and temperature management across diverse laboratory and production environments. The system integrates 16-bit technology with isolated digital and analog signal paths to minimize noise and cross-talk.
