Features

High definition imaging

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 this new CMOS image sensor and high-speed data transfer via USB 3.0, 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 for the capture of brighter images with higher S/N ratios in fluorescence observation modes.

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.
