Equipped with a Nikon digital SLR camera FX-format CMOS sensor optimized for microscopy, the DS-Qi2 is an ultra-high quality 16.25 megapixel monochrome camera that features high pixel density, high sensitivity and low noise. The DS-Qi2 is an excellent choice for applications in quantitative fluorescence imaging.
Key Features
Large format CMOS sensors
Nikon manufactures CMOS sensors and imaging technologies for professional D-SLR cameras, which are now optimized for microscopy.
High sensitivity
Detects even faint fluorescent signals
7.3µm pixels, high quantum efficiency, and very low read noise allow the DS-Qi2 to even read faint fluorescent signals.
Excellent linearity
Reliable quantitative analysis made possible
With a linearity error of ±1%, the DS-Qi2 is a superb tool for measuring intensities in fluorescence samples, including time-based intensity measurement and ratiometric measurement.
Low noise
Acquires dim fluorescent signals with ultra-low noise
2.2 electrons read noise, coupled with a large full-well capacity, allows for the acquisition of fluorescence images with very little noise and a very high dynamic range.
