Line of cooled cameras delivers low-noise images

OCTOBER 2, 2008--New cooled cameras with controlled double-stage Peltier cooling are designed for low-light applications with extremely long exposure times such as in fluorescence microscopy, astronomy, electrophoresis, and gel documentation.

OCTOBER 2, 2008--New cooled cameras with controlled double-stage Peltier cooling are designed for low-light applications with extremely long exposure times such as in fluorescence microscopy, astronomy, electrophoresis, and gel documentation. The cooled cameras feature a 2/3-in. CCD sensor and 12-bit pixel depth. Available interfaces are FireWire, Camera Link (also PCMCIA), or GigE. For virtually noise-free images, at room temperature the sensor is cooled to -15°C with the controlled double-stage cooling (unregulated max. DT = -42°C). Reduction of thermic noise enables low-noise signal (66-dB SNR) even for exposure times of several minutes. Readout noise can be reduced using Slow Scan Mode with a lower clock rate.

In a class of its own - virtually noise-free images!
The new "cooled cameras" with controlled double stage Peltier cooling provide unbeatable performance in all areas. They offer outstanding performance for low light applications with extremely long exposure times, e.g. in the area of fluorescence microscopy, astronomy, electrophoresis and gel documentation. The cooled cameras feature a high-quality 2/3"CCD sensor that stands out with its extremely high sensitivity, a high resolution and excellent quantum efficiency. The low-noise cameras work with 12-bit pixel depth. The interface can be chosen between Fire Wire, Camera Link (also PCMCIA) or Gigabit Ethernet. For virtually noise-free images: At room temperature the sensor is cooled to -15°C with the controlled double stage cooling (unregulated max. DT = -42°). The enormous reduction of thermic noise guarantees an almost noise-free signal (66 dB SNR) even for exposure times of several minutes. The electronic noise is minimized 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. The "signature cameras"are also available as cooled versions.

Kappa opto-electronics GmbH - Kappa opto-electronics, a medium-sized owner-managed company, provides high quality CCD cameras and image processing solutions for a wide range of applications with demanding requirements. Kappa is one of the few camera manufacturers with longtime experience in the development and manufacturing of extremely rugged cameras with above average signal quality. Today the organically grown company employs 90 people. Highly trained graduate engineers, computer scientists, mathematicians, physicists, and biologists provide a broad spectrum of expertise for future-oriented technologies.
