Apogee Instruments - Alta U16M Front-Illuminated CCD Camera with KAF-16803 Full Frame Sensor

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 KAF-16803 Sensor

The Kodak KAF-16803 image sensor is a redesigned version of the popular KAF-16801E image sensor (4096 x 4096 pixel resolution) with enhancements that specifically target the needs of high performance digital radiography applications. Improvements include enhanced quantum efficiency for improved DQE at higher spatial frequencies, lower noise for improved contrast in areas of high density, and anti-blooming protection to prevent image bleed from over exposure in regions outside the patient.

Utilizing Kodak's proprietary single gate ITO process and micro-lens technology, the KAF-16803 image sensor with its large imaging area and small pixel size provides the sensitivity, resolution and contrast necessary for high quality digital radiographs. To simplify device integration, the KAF-16803 image sensor uses the same pin-out and package as the KAF-16801E image sensor.
