US 2015/0311049 A1 · PHOTODETECTION UNIT AND METHOD FOR MANUFACTURING SAME

Abstract

In a photodetection unit 100 according to one aspect of the present invention, a photomultiplier 1 and a voltage divider board 132 are electrically connected to each other through a flexible wiring board 120, whereby the photomultiplier 1 can freely set its orientation and achieve a high degree of freedom of installation. In addition, in a voltage divider 130, an insulating resin 136 within a resin case 134 covers around the voltage divider board 132, thereby improving a voltage withstand performance of the voltage divider board 132. This eases restrictions on conditions under which the voltage divider board 132 is installed, whereby the degree of freedom of installation of the photodetection unit 100 is further improved as a whole, which makes it applicable to wider uses.
