DS-Qi2 camera - Digital Sight microscopy camera

DS-Qi2 microscopy digital camera equipped with a Nikon digital SLR camera FX-format CMOS sensor optimized for microscopy.

Benefits & features

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.

*1Conversion efficiency from light to electrical signals.
*2Noise caused by heat from the sensor during lengthy exposures.

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.
