PHOTONIS’ Advanced Performance Detectors (APDs) are plug-and-play electo-optic assemblies which provide a complete housing, facilitating manufacturing assembly, repair or replacement to mass spectrometers and other machines. Available for new machines or as replacement cartridges for existing models, over 200 types, with cartridge-mounted MCP, further simplifying additional repairs. ¶PHOTONIS Advanced Performance Detectors (APDs) satisfy applications ranging from mass spectrometry to UV and X-ray astronomy. Most of these detector assemblies are designed for use in ultra-high vacuum systems and the 300°C temperatures reached during chamber cleaning, therefore saving time that would otherwise be required to remove the detector. Readout schemes - including photodiode array, phosphor screen, CCD camera, or direct electrical signal - are available.
