Hamamatsu markets a 32-pixel packaged APD with a pixel size of 1.6 mm by 1.6 mm. To maximize light output, NO A utilizes a looped or U-shaped WLS fiber. Both ends of the looped fiber terminate on the same APD pixel. To comfortably accommodate both fiber ends, Hamamatsu has modified the pixel size and shape to match our requirements. ................
