The next generation of Ocus scanners: The Ocus M series

divider
Introducing the Ocus® M series, the innovative and advanced next step in our scanner lineup. This next-generation device leverages the familiar form factor and the compact design of previous Ocus® devices, while delivering higher throughput and advanced features.

Now available in both 20x and 40x versions.

Ocus M 40 (MGU-20008) and Ocus M 20 (MGU-20009) are for research use only (RUO) and not fod use in diagnostic procedures. Ocus M 40 (MGU-30008) and Ocus M 20 (MGU-30009) are CE-marked under the In Vitro Diagnostic Regulation (IVDR, EU 2017/746), making them approved for use in clinical and diagnostic workflows within the European Union.

We enhanced our ALREADY best-in-class image quality and CAPTURE

The Ocus® M series delivers enhanced image quality with its optimized illumination system and superior color reproduction, ensuring a level of consistency that you can reliably trust. The improved depth of field allows you to see better cellular detail in each field of view, providing clearer and more precise images for your analysis.

Its advanced image generation pipeline not only ensures faster processing but also delivers higher-quality image data, resulting in superior pixel clarity and detail that meet all your microscopy needs.

The upgraded stitching algorithm enables earlier access to images, allowing you to view the scanned areas while the rest is still being scanned, rather than having to wait until the entire scan is complete. This means less wait times and provides efficiency in your workflow.

Increased slide capacity,
easier slide handling

We listened to your feedback about increasing the slide capacity – and we delivered. The Ocus M series features a capacity of four slides, allowing you to do more walk-away scanning and spend less time loading slides.

Additionally, the slide tray is removable, ensuring easier slide handling and preparation. You can also access extra trays, allowing you to prepare a set of slides while another tray is being scanned, giving you more time to focus on other tasks or preparations.

Support for 2×3" slides

Soon, a tray option for larger, 2×3" slides will be available for the Ocus M devices.

Available in two versions

The Ocus M Series is available in two magnification options — 20x and 40x — so you can select the version that best fits your workflow. Both deliver the same exceptional performance, image quality, and features. The only difference is the level of optical magnification and image detail.

Choose 20x when you need faster scans and a wider field of view — perfect for overviews, routine histology, and high-throughput environments. Or opt for 40x when maximum detail is critical, such as in cytology, dermatopathology, or research requiring fine structural resolution.
  • Magnification: 20x
  • Scan resolution 0.25 μm / pixel
  • Numerical aperture: 0.40
  • Depth of field: 4.2 μm
  • Z-stacking: up to 7 layers (1 μm steps)
  • Magnification: 40x
  • Scan resolution 0.50 μm / pixel
  • Numerical aperture: 0.75
  • Depth of field: 1.3 μm
  • Z-stacking: up to 7 layers (0.25 μm steps)

ALL-NEW user interface 

More organized

The Ocus M introduces a redesigned, browser-based user interface that retains the familiarity you love while enhancing functionality from the ground up. With the ability to see slides organized by case, you can streamline your workflow and manage your samples more efficiently.

Advanced Security and Control

Role-based access control and permissions add an extra layer of security, ensuring that only authorized users can access and modify critical data. This feature helps maintain the integrity of your work and safeguards sensitive information.

Customizable Scan Profiles

The Ocus® M user interface features customizable and saveable scan profiles, allowing you to tailor scan settings and color preferences to your specific needs. This enhancement not only improves your workflow but also ensures consistent results across different scans.

Control and optimize your workflow

These features give you more control over your workflow and the ability to optimize processes, making the Ocus® M a powerful tool for any lab looking to improve efficiency and accuracy in slide scanning and analysis.
