1600 x 1200 pixel array

Nikon's DS-Fi3 is a new high-definition color microscope camera equipped with a 5.9 megapixel CMOS image sensor. Its high-speed data readout, superior color reproduction and high quantum efficiency are optimal for imaging in various observations, such as brightfield, DIC, phase contrast and fluorescence observation.

Benefits & features

High Definition Imaging

Liquid crystal panel (Objective: TU Plan Fluor 10x)The DS-Fi3 is equipped with a 5.9 megapixel CMOS image sensor, which enables the capture of high-definition images of up to 2880 x 2048 pixels. With a new CMOS image sensor and high-speed data transfer via USB3.0, the DS-Fi3 enables fast focusing even in high-resolution imaging, and efficient image acquisition when using a wide range of illumination techniques.

High Sensitivity and Low Noise

The DS-Fi3 has significantly higher quantum efficiency and lower readout noise than conventional models. It allows the capture of brighter images with higher S/N ratios in fluorescence observation.

High-speed Live Display

Due to the high-speed data readout by the CMOS image sensor and high-speed USB3.0 data transfer, the DS-Fi3 displays live images of full 2880 x 2048-pixel images at 15 fps, and 1440 x 1024-pixel images at 30 fps. This enables smooth display during focusing and the selection of observation locations.

Excellent Color Reproducibility

Nikon is well-known for outstanding and lifelike color reproduction, and developing superior algorithms for creating results that look like the actual samples. These algorithms are used in all of the color cameras in the Digital Sight lineup.

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.

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.

Benefits & features

One-shot capture of high-definition color images

DS-Ri2 offers 16.25 megapixels. The newly equipped CMOS sensor for Nikon FX-format digital SLR cameras (36.0 x 23.9 mm image size) enables one-shot capture of high-definition images. It also allows faster imaging than pixel shift imaging comprising multiple-shot images, and reduces vibration during image capture.

Superior color reproduction, high sensitivity and low-noise imaging

The newly developed image processing engine is ideal for brightfield imaging of pathological samples, which require high-color reproducibility. The large pixel size (7.3 um pixel pitch) allows weak light to be captured by each pixel and the low-noise circuit design is optimized for microscope imaging. These enable sensitivity control from ISO200 to ISO12800, and high-sensitivity fluorescence imaging with reduced noise.
