The Newport 8605 is a dual-function module that combines a 500 mA laser diode driver (LDD) with a thermoelectric cooler (TEC) controller in a single plug-in unit. Designed for the Newport 8000 Series modular controller mainframe, it delivers precise current control for laser diodes and accurate temperature stabilization to maintain optimal laser performance. The module integrates advanced 16-bit technology for high-precision control and measurement, with automatic mainframe detection and configuration display.
