High quantum efficiency The CCD sensor provides 2048 x 2048 pixel resolution with a 14-bit dynamic range. The full-frame CCD chip offers a pixel size of 14 µm x 14 µm with an active area of 28.7 mm x 28.7 mm. With a dark current of < 0.6 e-/p/s, a full well capacity of about 250,000 electrons, a read-out noise of approximately 8 electrons and its water-cooled system, the high sensitivity of the CantegaG2 allows observation of samples on the monitor at beam intensities so low, they would normally prohibit a user seeing anything at all on the TEM viewing screen. Convenient frame rates The CantegaG2 supports two readout rates at 14 bits. The 2 MHz mode produces images of the highest quality at convenient frame rates. In the high speed 5 MHz mode the camera offers about 6 frames per second at binning 4 and 1 frame per second at full resolution. At any resolution, this camera provides a superb dynamic range and sensitivity. Binning modes of 2x, 4x and 8x are supported by the CantegaG2. This means that sensitivity can be increased even more.
