Capture low light fluorescence and large fields of view
Large format CMOS sensors
Nikon manufactures CMOS sensors and imaging technologies for professional D-SLR cameras, which are now optimized for microscopy.
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.
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.
High frame rate
Fast focusing, even with fluorescent images
Both 2.2 electrons read noise coupled with a large full-well capacity and 0.6 electrons dark current allow the acquisition of fluorescence images with very little noise.
Acquires dim fluorescent signals with ultra-low noise
2.2 electrons read noise, and this, coupled with a large full-well capacity, allows the acquisition of fluorescence images with very little noise and a very high dynamic range.
LLC-PK1 cells expressing GFP-EB3 tubulin Low noise and large linear full well capacity allows the acquisition of large dynamic range in a single capture.
A captured image is shown intensity scaled to show both the brightest and dimmest areas.

Fluorescent time-lapse imaging through integration with NIS-Elements software
With a large field of view and pixel density, and low noise, the DS-Qi2 is ideal for time-resolved imaging applications.
