Hamamatsu Photonics (Bridgewater, NJ) has introduced the ORCAD2, a dual CCD camera that can capture simultaneous dual wavelength or multiple focal plane images. Each CCD captures a 1280 (H) x 960 (V) pixels field of view, and each CCD has independent exposure and gain settings, making it suitable for FRET and ratio imaging applications. One of the CCDs is adjustable via software to compensate for vertical, horizontal, and Z-axis registration. Each optical block can be adjusted for multiple objective choices as well. When the optical block is inserted into the camera, the position of the moveable CCD is automatically adjusted for the optical setup. It also features high sensitivity and low noise, vacuum-sealed chamber technology, and wide dynamic range. An IEEE1394b interface, 12-bit A/D converter, and various external trigger modes are also included.
