<p><P>PROBLEM TO BE SOLVED: To provide a spectrophotometer for measuring the radiation spectrum of an external light source, which eliminates the need for a dedicated inlet for introducing external light and an optical axis switching mechanism for switching an optical axis. <P>SOLUTION: The spectrophotometer exchangeable of an internal light source is, after removing the internal light source, installed with an external light introduction optical apparatus 4 which is attachable/detachable to/from a light source positioning component (not shown) and includes an external mirror 5 and an internal mirror 6. The external mirror 5 includes an optical axis adjustment axis 7 for directing its mirror surface toward the external light source, thereby performing measurement with the external light source is installed without requiring to attach it to a dedicated holding mechanism. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
