LabQ User Interface

The ProteusQ-LT is fully integrated with our LabQ software interface, providing the same consistent and reliable platform used across the ProteusQ product line.

Built on the open-source Qudi framework, LabQ offers an intuitive environment for working with multiple measurement modalities. Years of development across our platforms ensure a stable, feature-rich, and well-tested toolset.

Key features

  • Unified interface – A consistent workflow across all ProteusQ systems.
  • Automation – Streamlined alignment and routine procedures.
  • Advanced capabilities – Powerful tools to support complex experimental setups.

The result is a microscope and software ecosystem designed to make advanced measurements more accessible, efficient, and reproducible.
