These low-light imaging detectors offer high sensitivity at near-IR wavelengths.

Ravi Guntupalli, Princeton Instruments

Thanks to advanced sensor and camera technologies, scientific low-light imaging detectors now boast more than 90 percent quantum efficiency, <1 electron root-mean-square read noise and negligible dark current. Although standard and electron-multiplying CCD cameras perform well in the ultraviolet-to-visible region, they pose unique limitations in the near-infrared (700 to 1100 nm). The availability of cooled deep-depletion CCD cameras is filling the gap and enabling scientific research, development and process control fields in such disparate applications as solar technology, astronomy and...Read full article
