High Resolution Digital B/W CCD Camera, ORCAII-ER
The ORCAII-ER camera features the unique ER-150 CCD chip packaged in a proprietary permanently sealed vacuum chamber evacuated to 10 -7 Torr. This CCD offers very high quantum efficiency over the spectrum from 350 nm to 850 nm and very low noise. With selectable full well capacity, low read noise, cooling to – 60°C to virtually eliminate dark current, this camera will produce rapid exposures and high dynamic range images. Dual mode digitization offers a software selectable choice of speed or very low noise readout methods with 12 and 14 bit precision. Special analog contrast enhancement circuits increase versatility for even the most difficult imaging conditions.
