Photosensitive area structure suitable for spectrometers, high-speed type
The S14651/S14661 series are back-thinned CCD image sensors designed for spectrometers. Low-noise type (S14651 series) and high-speed type (S14661 series) are available. The S14650/S14660 series offer nearly flat spectral response characteristics with high quantum efficiency from the UV to near infrared region. A thermoelectric cooler is placed inside the package to keep the chip temperature constant (approx. 5 °C) during operation.

Features
– One-stage TE-cooled type (chip temperature: approx. 5 °C)
– Low etaloning
– High sensitivity over a wide spectral range and
nearly flat spectral response characteristics
– High conversion efficiency: 8 μV/e-
– High full well capacity and wide dynamic range
(horizontal shift register with anti-blooming function)
– Pixel size: 14 × 14 μm
