Alta U47 CCD Camera - Class 1

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.
