SUMITOMO HEAVY INDUSTRIES TECHNICAL REVIEW
Xenon Lamp Power Supplies XPD Series
Hiroyuki SHIMOKAWABE

Xenon lamps are used as the light source for measurement since they have smooth spectral characteristics from infrared to ultraviolet, as well as high intensities. Measuring instruments are required to have very high stability since the stability of luminous energy directly affects their measurement accuracy. The recent demand for stable light sources that respond to increased measurement accuracy is so strong that it cannot be met with conventional light source products. The power supply device that SHI Control Systems, Ltd. recently developed achieves a high level of stability, which has been impossible with conventional products.
