The Rapid Automated Modular Microscope (RAMM) system from Applied Scientific Instrumentation (Eugene, OR) allows a custom system to be easily developed. The microscope is configurable with infinity-corrected optics, filter cubes, filterwheels, and detectors. Automated features include high-speed XY stages, piezo and motorized focusing, auto-focus, and a robotic specimen loader. The system provides a solid platform for flexible OEM development using high MTBF components.
