Patent number: 7141803Abstract: A scintillator panel 1 uses a glass substrate 5, having heat resistance, as a base member for forming a scintillator 10. Glass substrate 5 also functions as a radiation entry window. Also, a dielectric multilayer film mirror 6 is disposed as a light-reflecting film between the scintillator 10 and the glass substrate 5. Furthermore, a light-absorbing film 7 is disposed on the radiation entry surface of glass substrate 5 and this absorbs the light that has been emitted from scintillator 10 and has passed through the dielectric multilayer film mirror 6 and the glass substrate 5. Light components that are reflected by the radiation entry surface, etc., and return to the dielectric multilayer film mirror 7 and the scintillator 10 therefore do not occur and the optical output of the scintillator panel 1 is not subject to degrading effects.Type: GrantFiled: September 11, 2001Date of Patent: November 28, 2006Assignee: Hamamatsu Photonics K.K.Inventor: Takuya Homme

Patent number: 7087908Abstract: Scintillator panel (1) comprises a radiation transmitting substrate (5), which has heat resistance, a dielectric multilayer film mirror (6), as a light reflecting film and is formed on the radiation transmitting substrate (5), and a scintillator (10), disposed on the dielectric multilayer film mirror (6) and emits light by conversion of the radiation (30) that has been made to enter the radiation transmitting substrate (5) and has passed through the dielectric multilayer film mirror (6). Since the radiation transmitting substrate (5) has heat resistance, the dielectric multilayer film mirror (6) can be vapor deposited at a high temperature and, as a result, can be formed in a state of high reflectance. Also, unlike a metal film, the dielectric multilayer film mirror (6) will not corrode upon reacting with the scintillator (10).Type: GrantFiled: September 11, 2001Date of Patent: August 8, 2006Assignee: Hamamatsu Photonics K.K.Inventor: Takuya Homme
