Are you tired of wasting your valuable time traveling between locations or waiting near the operating room for the samples? Would you prefer to be able to get a second opinion from your colleague in challenging cases even intraoperatively?

Have an Ocus® scanner in a lab near the operating room, and view the frozen section samples on your screen within minutes – and ask your colleague to participate, wherever they are. Utilizing Ocus® digital scanners saves your time for the most important part of your work and makes patient care faster and more precise.


High-quality images from frozen section slides

Ocus®20 boasts a patented imaging technology that guarantees sharp and clear images, even on uneven frozen section samples. This ensures that you maintain the quality of your scans. Moreover, our scanner strikes an excellent balance between image quality and scan speed, ensuring efficient operations.

Compact design

One of the unique features of our scanner is its horizontal placement of slides, which significantly minimizes spillage from wet slides, making it ideal for labs that handle delicate samples. The open-construction design of our scanner not only enhances its aesthetic appeal and makes it incredibly easy to clean the stage. If you're concerned about space, you'll be pleased with Ocus®20's compact design, making it a perfect fit even in the most cluttered labs.

Remote use enables easy collaboration

Our user interface is designed with the end user in mind. It's easy to use and intuitive, ensuring that even those who aren't tech-savvy, can easily navigate it. One of the standout features of the scanner is remote use. A pathologist can remotely log into the scanner at a suitable time and view the images stored on the device to assess them. The possibility to use the scanner remotely means that teams can collaborate in real time without any hitches.

Integrability to existing workflows

If you have existing systems in place, the images from Ocus®20 can be easily transferred to them, ensuring a smooth transition and workflow. Our platform offers the flexibility to export data in the most common file formats used in digital pathology (.svs and .tiff), ensuring compatibility and ease of data sharing across various platforms.

File formats supported by Ocus scanners are .svs, .tiff and .jpg
