Raptor Photonics Ltd. has introduced a 4.2-megapixel cooled scientific CMOS camera. The Osprey OS4MPc-CL features a 2k x 2k low-noise 2048 x 2048-pixel scientific CMOS sensor that produces high sensitivity, high resolution, high speed and good quantum efficiency. It is Peltier-cooled to —20 °C, uses a 12-bit analog-to-digital converter and offers standard Camera Link output. The camera is suitable for use in low-light applications, such as hyperspectral, high-resolution fluorescence and live-cell imaging; biochemiluminescence, astronomy, electrophoresis, x-ray and hyperspectral imaging. Features include an active pixel size of 5.5 x 5.5 µm, up to 37.5-Hz full-frame 12-bit Camera Link output, and dimensions of 86 x 65 x 61 mm.
