  • Resolution: 2.3 megapixels (1920 x 1200 effective pixels).
  • Pixel size: 5.86 µm, ideal for enhanced sensitivity and precise tracking.
  • Front-illuminated structure (FSI) with PregiusTM technology for CCD-like performance.
• Native sampling depth :
  • 12-bit ADC with output in 16-bit or 8-bit formats.
• Full Well Capacity :
  • Up to 32 ke-, for capturing high-contrast scenes without saturation.
• Low reading noise :
  • Between 1.6 e- and 5.3 e-, offering excellent image quality even in low light.
• Exposure time :
  • Adjustable exposure range from a few microseconds to several seconds.
• Global shutter :
  • Eliminates distortions caused by rapid movements or atmospheric agitation during planetary or lunar imaging.

Optical Performance
