The Automated Goniometer Head (AGH) provides the ability to center samples on a single crystal diffractometer with motorized alignment using auto centering software. The AGH offers a simple magnetic mount to pop the sample into place, followed by user-friendly software aided alignment using the system's software suite.
Researchers choose to guide the optical centering by clicking on the visual centroid of the crystal shape displayed on the video image or to have the system automatically center the crystal sample in the X-ray beam.
Components:
- Three-motor automated goniometer head with magnetic mount compatible with pins meeting ALS and SPINE standards
