1625萬畫素 高解析度 高感光度之彩色CCD
全片幅CMOS感光元件 低噪訊

Nikon manufactures CMOS sensors and imaging technologies for professional D-SLR cameras, and they have now optimized for microscopy.


High-resolution images
16.25-megapixel CMOS sensors for astonishing image quality

The DS-Ri2 makes possible one-shot instantaneous capture and fast storage of images with a resolution as high as 4908 x 3264 pixels, without pixel shifting or pixel stepping.
This pixel density is ideally suited for the photomicrography of ultra-fine structures or patterns in biological or industrial samples, at low or high magnifications.

Photography with the natural colors seen through the microscope
Nikon is a leader in development of algorithms for reproducing color just as the eye sees it.

The DS-Ri2’s new image processing engine is based on extensive data accumulated over many years of developing color, digital microscope cameras, resulting in the perfect reproduction of the colors your eyes see, in the microscope.

High-speed live display
High-speed display, even of supra-HDTV-class live images

The DS-Ri2 can display 4908 x 3264 pixel (full-pixel) images at 6 fps, or 1636 x 1088 pixel (3 x 3 pixel averaging) images at 45 fps.
This fast live frame rate makes fine focusing easy to perform.

High sensitivity, low noise
Fluorescent color image capture with high signal-to-noise ratio

Sensitivity settings that span the range from ISO200 to ISO12800, allow the capture of vivid fluorescent color images.
