C4742-98-26LA2	ORCA II BT 512, Air cooled, -65°C, 16 bit, RS 422 output

Click image to enlarge	The ORCAII -BT-512 features an original and unique Hamamatsu S7170 CCD chip packaged in a proprietary permanently sealed vacuum chamber evacuated to 10-7 Torr. This high resolution, back thinned, back illuminated CCD offers very high quantum efficiency over the spectrum from 200 nm to 1100 nm. With a huge full well capacity, low read noise and MPP (Multi-Pinned Phase) technology in the drive circuits to reduce dark current, this camera will produce rapid exposures and very high dynamic range images. Dual mode digitization offers a software selectable choice of speed or very low noise readout methods with 12 to 16 bit precision. Special analog contrast enhancement circuits increase versatility for even the most difficult imaging conditions.
