DS Qi2

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.
