Laser Controller
The Lambda Beam laser head requires a laser controller to provide power and control all operating parameters. For scientific applica- tions and prototyping we recommend using our PowerController. For industrial integration we also offer the highly compact Pow- erBox to be directly attached to the laser head or connected via a customized cable.
