Kappa has released a range of cooled cameras with controlled double stage Peltier cooling. The cameras offer high performance for low light applications with long exposure times, for example in the area of fluorescence microscopy, astronomy, electrophoresis and gel documentation.
The cooled cameras feature a 2/3-inch CCD sensor with high sensitivity, high resolution and excellent quantum efficiency. The low-noise cameras work with 12-bit pixel depth with options of FireWire, Camera Link (also PCMCIA) or Gigabit Ethernet interfaces.
At room temperature the sensor is cooled to -15°C with the controlled double stage cooling. The reduction of thermal noise guarantees an almost noise-free signal (66dB SNR) even for exposure times of several minutes. The electronic noise is minimised due to the use of high-quality components and intelligent circuitry. Furthermore, the readout noise can be reduced using the slow scan mode with a lower clock rate.
