Apogee Alta F42: Compact, 4.2 Megapixel CCD
Ideal for OEM and astronomy applications, the Apogee Alta family has been a mainstay of high end imaging for many years, offering a wide range of full frame and interline CCDs. Cooling performance down to 500C below ambient ensures optimal signal to noise for long exposure applications. A USB 2.0 interface offers the convenience of simple, robust connection to PC.
The Alta F42 has a back-illuminated full frame 4.2 megapixel CCD with very high quantum efficiency (>90% @550nm) and without anti-blooming structures to further improve sensitivity. The midband coating provides the highest peak in the visible range. Cooling down to 50oC below ambient results in a low dark current contribution. These features combine to make the Alta F42 an exceptionally versatile performer, and an ideal solution for many astronomy or physical science applications that require high sensitivity and a large field of view.
