Alta U2000 Specifications   Printer friendly PDF Alta U2000 Specifications The Alta U2000 is a 2-megapixel interline sensor with high quantum efficiency and twice the dynamic range of similar Sony sensors. Low noise and small pixels are ideal for OEMs, biological sciences, microscopy, and fundus imaging. Available with a monochrome CCD (U2000) or a color CCD (U2000C). 1600 x 1200 array, 7.4 x 7.4 micron pixels 10 MHz 12-bit and 1 MHz 16-bit digitization 32Mbyte camera memory Fast image sequences separated by as little as 1 microsecond USB 2.0 interface: no plug in cards or external controllers Programmable, intelligent cooling to 55C below ambient Binning up to 10 Horizontal x 1200 Vertical Subarray readout and fast sequencing modes Programmable fan speed for low / zero vibration Two serial port outputs for control of peripheral devices General purpose programmable I/O port External triggering and strobe controls ActiveX drivers included with every system Field upgradeable firmware Self-test capability with data simulators Fused silica windows Runs from single 12V supply with input voltage monitor Compact enclosure Programmable status indicators MaxIm DL/CCD and CCDSoft software packages are offered at special prices when purchased at the same time as a camera system.
