UK-based Hamamatsu Photonics has launched its full frame transfer CCD (FFT-CCD) imaging sensors in the S11510 range featuring extreme sensitivity in the near-IR light spectrum. By employing the company’s patented laser processing technology, a microelectromechanical systems design on the rear side of the CCD imager can be obtained, providing ultra-high sensitivity to wavelengths greater than 800 nm in length.

The quantum efficacy of these CCD sensors at 1000 nm is 40%, eliminating a deep depletion configuration, but supplies greater dark signal. These can be accessed with 1024 or 2048 pixels, having a 14 × 14 µm range for each pixel.
Apart from its intensive IR spectrum sensitivity, these sensing devices can be deployed for a broad sensitive zone in the direction of the sensor height. This characteristic can be attained through binning and can thus be ideally employed for Raman spectroscopy applications. These also have low etalation problems that are usually associated with Raman applications, demanding smooth and constant output.
The S11510 range is identical in configuration to the traditional S10420-01 FFT-CCD, where both these models are pin-compatible, facilitating its functioning under the similar drive applications. This feature helps enhancing the near-IR flexibility of a prevailing spectrometer or imaging sensor.
