What our customers say

The Philips IntelliSite Digital Pathology Solution has the capabilities to upload, view and annotate the images produced from the Grundium scanner. Zooming and panning is really fast, even when the images are physically stored on a server in the Netherlands and I’m viewing the images from a workstation in Sweden.

We have excellent images with the Ocus and I couldn’t be happier to have this little helper on my desk here. I use it mainly as a microscope, to be honest, but of course, scan my slides as well. It has really helped me so much.
