ULTRAVIOLET RADIATION/VISIBLE LIGHT SEPARATION TYPE PHOTODETECTOR

摘要

PROBLEM TO BE SOLVED: To provide an ultraviolet radiation/visible light separation type photodetector capable of simultaneously measuring ultaviolet radiation and visible light at the same place, and to provide the ultraviolet radiation/visible light separation type photodetector by which miniaturization and cost reduction is possible. ;SOLUTION: The ultraviolet radiation/visible light separation type photodetector is obtained by superposing and integrating an ultraviolet radiation photodetector 20 of a visible light transmitting type and a visible light photodetector 27.;COPYRIGHT: (C)2003,JPO
