The ILX Lightwave LDT-5910 is a benchtop thermoelectric temperature controller delivering precise thermal management for laser diodes, IR detectors, and other sensitive optical components. Operating with up to 4.6 A output current and 15 W typical power, the unit maintains temperature stability of ±0.01 °C with settling times under 5 seconds. Its three control modes—Constant Temperature, Constant Sensor, and Constant Current—accommodate diverse thermal requirements. The LDT-5910 accepts thermistor, RTD, and IC sensor inputs, offering 0.1 °C display resolution and real-time parameter monitoring via 7-segment LED and dot matrix display.
