Enhanced Near-IR Sensitivity Back-Thinned CCD for Astronomy Applications Mar 3, 2009

Hamamatsu has introduced the new S10747-0909 fully depleted back-thinned CCD image sensor, which has been specifically developed for low light level measurement. This new device is available with 512 by 512 pixel quantity, and individual pixel size of 24 µm by 24 µm. The device features a superb spectral response range from 300 nm to 1200 nm, with quantum efficiency (QE) greater than 90% at its peak. A typical CCD exhibits virtually no sensitivity at 1000 nm, whereas the new S10747-0909 exhibits a QE of 70%! In fact, the QE is significantly improved over the whole range from 400 nm to 1200 nm compared to a typical back-thinned CCD image sensor. This makes the S10747-0909 suitable for a wide range of applications, but particularly as a detector for near-IR imaging of astronomical objects.
