NDP.view2 Image viewing software


NDP.view2 provides excellent followability and intuitive operability. You can observe images to the details like a microscope. Additionally, 

it supports more than 10 languages, including Japanese, English, Chinese, and more. 

Intuitive operation

Comparable to a map application, allowing you to zoom in and out, and rotate the image.

Annotation function

Inserts arrows, drawings, and comments. Also measures the length and surface area of specified point.

Multiview function

Ability to display multiple images simultaneously opens new possibilities that were previously unavailable with microscopes. This feature allows you to examine the details while maintaining a broader perspective, making it easier to compare different stains in the same viewer. Additionally, the digital slides can be synchronized, to enhance user experience.
