Sep 2018TAUFKIRCHEN, Germany, Sept. 13, 2018 — FRAMOS GmbH has announced the Interline Transfer EMCCD KAE sensor line from ON Semiconductor, designed for high-quality imaging in extreme low-light conditions.

The KAE-08152 is a 4/3-in. imager with an 8.1-MP resolution that provides increased quantum efficiency, specifically for NIR wavelengths. The low-light imaging performance of the sensor is a perfect fit for surveillance, intelligence transportation systems, and scientific and medical applications. Sub-lux imaging is enabled by interline transfer EMCCD technology. Each of the sensor's four outputs incorporates both a conventional horizontal CCD register and a high-gain EMCCD register, resulting in exceptional low-light imaging performance.

The KAE-08152’s quantum efficiency is doubled at approximately 850 nm compared to the standard KAE-08151 to provide enhanced NIR sensitivity without any decrease in the device's modulation transfer function (MTF). An intrascene switchable gain feature samples each charge packet on a pixel-by-pixel basis, enabling the camera system to route charge through the normal gain output or the EMCCD output depending on a user-selectable threshold.More products
