S5668 series
S5668-021
The S5668 series is a 16-element Si photodiode linear array. Each element has an active area of 1.175 mm (width) × 2.0 mm
(height) and is arrayed at an element pitch of 1.575 mm. The entire linear array is mounted on a 25.4 mm (1 inch) long PC
board. By linearly arranging two or more pieces of the S5668 series, a long and narrow photodiode array can be easily congured
at the same element pitch. For X-ray detection applications, the S5668-121 with a CsI (Tl) scintillator, the S5668-321 with a ce-
ramic scintillator and the S5668-421 with a uorescent paper are also available.
