With photo-sensitive electron tubes, we strive constantly to improve the basic performance of the product, by boosting sensitivity, reducing noise, and expanding the range of detectable wavelengths. At the same time, we are always looking for new and useful ways in which the product can be utilized. In recent years, by combining electron tube technology and semiconductor technology and by bringing crystal photocathodes into practical use, we are finding potential new markets for product development to meet needs. Light sources are widely used in many fields, among them semiconductor manufacturing, factory automation, information industries, and environmental applications, and we are constantly working to develop new products with higher performance levels. Our deuterium lamps employ a special construction that gives them a longer lifetime than any other type, while our μfocus x-ray light source for non-destructive testing is highly acclaimed for its sharp, enlarged fluoroscopic images. Our UV spotlight sources, used in the bonding of optical components, are likewise highly rated. These and other Hamamatsu products have been quick to find their niche in today's market because they meet specific needs.
