Laser Diode Controller Guide

Precision Control of Laser Drive Current & Temperature in One Instrument

Combination Laser Diode Controllers have both a precision Laser Diode Driver, and Laser Diode Temperature Controller in a single instrument. This helps to save valuable space, as well as providing for temperature and current information of a laser diode in one location. We also offer Modular Laser Diode Controllers that can be configured as laser diode drivers and temperature controllers for many devices at once. To complement our combination laser diode drivers and TEC temperature controllers, we also offer a complete line of Laser Diode Mounts and fixtures with plug and play compatibility with our drivers and temperature controllers.
