Title:
Radiation image detecting device
Document Type and Number:
Japanese Patent JP5996478
Kind Code:
B2
Abstract:
A radiation image detecting device 20 includes a photodetecting element 10 that detects fluorescence light, and a prism 5 that is disposed on an optical path of excitation light EL traveling toward an imaging plate IP and between the photodetecting element 10 and the imaging plate IP. The prism 5 includes, as surface thereof, a side face 5c that is opposed to the imaging plate IP, and a side face 5a and a side face 5b that are inclined relative to the side face 5c. The prism 5 is disposed so that the excitation light EL incident through the side face 5a propagates inside and is output from the side face 5c and so that reflection from the imaging plate IP incident through the side face 5c propagates inside and is output from the side face 5b. The photodetecting element 10 is disposed so as to be opposed to a region different from a region where the reflection from the imaging plate IP is output, in the surface of the prism 5.
