ATLAS Adapter
The base module comes equipped with a standard DE9 connector. We offer an add-on module featuring connectors for power, communication (USB-C) and trigger signals (SMA).
To meet laser safety standards, this module adds key control and a remote interlock connector.
Intuitive Software for Seamless Laser Operation
For intuitive operation and control, we provide a software interface which includes a graphical user interface (GUI) for straightforward wavelength setting and tuning, along with a Python library for advanced laser control functions.
