Alta U30 Specifications   Printer friendly PDF Alta U30 Specifications The Alta U30 has a back-illuminated full frame spectroscopy format CCD with exceptionally high quantum efficiency. The standard midband coating (U30-MB) has the highest peak in the visible; the optional broadband coating (U30-BB) has somewhat higher QE in the near UV but lower QE across the visible. The UV-enhanced version (U30-UV) has the highest QE in the UV (See the quantum efficiency curve) 1024 x 256 array, 26 x 26 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 256 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 and MaxIm DL/CCD software 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.
