Overview
Ice Bloc DD40 is a high-power, precision laser diode driver - available with a choice of 1 to 4 independent channels-designed to help you build laser-based photonic systems for research, experimental and production applications.
Driving the latest generation of high power laser diodes, the DD40 combines high current (up to 40A), low noise output with high accuracy and high-resolution current set points. Its compact form factor with customisable software interface allows easy integration of the DD40 into experiments or OEM setups
