The Alta Design Team at Apogee worked hard over a two year period to bring this advanced degree of integration and performance to the astronomy market. Alta has set new standards for imaging performance, connectivity, cooling, compactness, cost effectiveness, and the elimination of external support electronics. Like the AP and KX series, Alta is a platform, not a CCD or specific interface type. It is designed for a variety of CCDs, ranging from the smallest to those measuring 36mm on a side with 4096 x 4096 arrays.
So many improvements in such a small package: No more external controllers, plug-in cards, or frame grabbers. Dual digitization for high precision plus high speed focus. On-board camera memory for fast local sequences and no worries about transfer interruptions. Time delayed integration for imaging far beyond the size of the sensor. A single 12V power input for optional battery-powered operation. In addition, the Apogee Alta U Series cameras have dual digitization, 12 and 16 bit. The 12 bit mode is intended primarily as a focus mode.
Alta U Series cameras are available with a wide variety of sensors, including: Back-illuminated sensors with very high quantum efficiency, some with sensitivity in the deep UV; Interline transfer sensors with fast electronic shuttering and inherent anti-blooming; front-illuminated CCDs with high sensitivity in the near-IR without etaloning. In general, the larger the pixel size, the higher the dynamic range. Smaller pixels (about 7 microns) are typically used for microscopy (U32; U2000; U4000); larger pixels and larger arrays are typically used for astronomy (U42, U47 back-illuminated; U16M, U9000, U6 front-illuminated).
Apogee Alta Scientific Imaging Systems means you'll get High Speed, low noise, 16/12 bit dual digitization to 7 MHz, TEC cooling to >75C. Lifetime warranty on CCD chamber seal. Fast USB 2.0 advanced I/O control. The Apogee Alta imaging systems represent cost effective advanced imaging technology not found anywhere else. The Alta platform currently supports 11 different housing configurations, including high cooling, wide entrance angle, and low profile variants, many with a choice of fans or liquid circulation.

About the Kodak KAI-2020 Imaging Sensor
The Kodak KAI-2020 Image Sensor is a high performance 2 million pixel sensor designed for a wide range of medical, scientific and machine vision applications. The 7um square pixels with microlenses provide high sensitivity and the large full well capacity results in high dynamic range. The split horizontal register offers a choice of either single or dual output allowing either 18 or 35 frame per second (fps) video rate for the progressively scanned images. Also included is a fast-line dump for sub-sampling at higher frame rates. The vertical overflow frame structure provides anti-blooming protection and enables electronic shutter for precise exposure control. Other features include low dark current, neglibible lag and low smear.
