The PMT module is basically comprised of a photo-multiplier tube to convert light into electrical signals, a high-voltage power supply circuit, and a voltage divider circuit to distribute the optimum voltage to each dynode, all assem-bled into a single compact case. In addition to these basic PMT modules, Hamamatsu also provides modules having var-ious additional functions such as signal processing, cooling and interface to PC.

Xenon lamps emit a continuous spectrum with high luminance and high color temperature, ranging from the UV to visible to infrared range. Xenon lamps are therefore ideal for various types of photometric equipment such as spectro-photometers. All of our xenon lamps employ a high-performance cathode that eliminates the problems of con-ventional lamps and are widely used in applications where high-precision measurement lamps are needed.
