REVOLON TEM Scan Controller
REVOLON TEM Scan Controller with open access and Python sample code
The REVOLON TEM Scan Controller defines new benchmarks with open access, high-performance functions, free scan patterns and compatibility with all major TEM models.
The TEM Scan Controller is based on our high-performance Digital Imaging Scanning System and is specifically prepared for researchers, developers or SMEs that require independent equipment or technique development in TEM.
✅ designed for, and tested, on all major TEM manufacturer external scan interfaces
✅ sample code is provided for Python, C and C#
✅ Full hardware control with the API documentation over conventional image scans, pixel map scans and hardware syncronisation with 4D STEM detectors and imaging cameras
✅ analog channels for conventional BF, HAADF and similar detectors
✅ digital channels for pulse processors.
