Nikon DS-Qi2 16.25 Monochrome CMOS Camera

Nikon Camera DS-Qi2 16.25 Monochrome CMOS

Capture low light fluorescence and large fields of view.

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.

High sensitivity and low noise

The newly developed 16.25-megapixel monochrome CMOS sensor for the monochrome digital camera for microscopes offers 36.0 x 23.9 mm image size.

The S/N ratio is five times better than that of conventional models, with quantum efficiency*1 up to 77% and 2.2-electron readout noise. In addition, Peltier cooling (electronic cooling) reduces dark-current noise*2 and produces clear images with reduced noise even with dark fluorescent specimens.

Superior quantitative performance

Low ± 1% linearity error of output power to input light intensity enables correct measurement of changes in brightness of specimens.

High-speed live-image display

Thanks to the USB3.0 computer connection and CMOS sensor, which provides high-speed data readout, the frame rate has been significantly improved to 45 fps (1636 x 1088 pixels), from 19 fps (1280 x 1024 pixels) with conventional models. This enables fast live-image display and easy observation point selection and focusing.
