Ultrasensitive scientific cameras from Fairchild Imaging are suitable for imaging applications that require quality performance in low-light conditions. Utilizing large-area CCD technology, the devices are built to function with the company's 2k × 2k and 4k × 4k sensors in both front- and back-illuminated versions. Speed and sensitivity are attained with a low-noise, dual-speed multiport readout system, and deep thermoelectric cooling to –60 °C nearly eliminates dark current. The cameras have a linear, 16-bit dynamic range and offer functions such as antiblooming control and software control over binning and gain. They feature hard metal seals for reliable vacuum and low-maintenance operation. Available with standard lenses and mounts, they also can be configured for x-ray and electron imaging with bonded fiber optic tapers up to 200 mm in diameter.
