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; U16, U6 front-illuminated).
