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 S5668 series, a long and narrow photodiode array can be easily configured at the same element pitch. For X-ray detection applications,
S5668-11 with a CsI (Tl) scintillator and S5668-34 with a ceramic scintillator are also available.
