Nikon DS-Ri2 HD Digital Microscopy Camera

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.

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.

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 the conventional model. This enables fast live-image display and easy observation point selection and focusing.
