Alta U47 Specifications   Printer friendly PDF Alta U47 Specifications The Alta U47 has a back-illuminated full frame megapixel CCD with exceptionally high quantum efficiency. The standard midband coating (U47-MB) has the highest peak in the visible; the optional broadband coating (U47-BB) has somewhat higher QE in the near UV but lower QE across the visible. The UV-enhanced version (U47-UV) has the highest QE in the UV (See the quantum efficiency curve) 1024 x 1024 array, 13 x 13 micron pixels 2 MHz 12-bit and 700 kHz 16-bit digitization 32Mbyte camera memory USB 2.0 interface: no plug in cards or external controllers Programmable, intelligent cooling to 55C below ambient Binning up to 10 Horizontal x 1024 Vertical Subarray readout and fast sequencing modes Precision time delayed integration readout 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 (other software sold separately) Field upgradeable firmware 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.
