Photomultiplier system for use in confocal scanning microscope, has power supply unit providing accelerating voltage, where detector tube and power supply unit are disposed on different sides of thermal isolation unit

摘要

The system has a power supply unit (2) providing an accelerating voltage for operating a detector tube (1). The detector tube and the power supply unit are disposed on different sides of a thermal isolation unit. The power supply unit and the isolation unit are coupled via a support unit. A printed circuit board has a flexible region connecting one of the power supply unit or support unit.
