VisionTek® Digital Microscope

Real-time slide review for Anatomical Pathology

The VisionTek® Digital Microscope is a robotic imaging system that pathologists can use like a conventional microscope to view live up to 4 slides simultaneously or view multiple areas of the same slide at different magnifications (2.5x, 10x, 20x, 40x). Time to view is under 17 seconds. The VisionTek® Digital Microscope is the ideal live or scanned slide review system for anatomical pathologists to use for intraoperative or second-opinion consults.

The VisionTek® Digital Microscope incorporates a motorized brightfield optical system, together with multiple cameras, automated XYZ, IR and image-based autofocus to convert optical fields of view of specimen on glass slides, at various magnifications, into high-resolution digital images that are displayed in real time on a high-resolution monitor for ergonomic viewing.

The system is operated via software through a PC interface and can also be controlled remotely via the internet so live images can be shared by multiple remote viewers. The VisionTek® Digital Microscope is also capable of rapid scanning of multiple Z planes of partial slides (PSI™) or whole slides (WSI) for archiving and sharing, making it a truly versatile instrument for anatomical pathologists.

The snapshot, partial scan, and whole slide scanned images are for research use only (RUO) in the USA.

For intraoperative consultation



Time to live review under 17 seconds
  • Review urgent intraoperative cases within minutes
Robotic control of microscope stage, focus, magnification, and illumination with a mouse
  • One-hand operation as with a microscope
Remote control
  • Review slides interactively from any location without having to travel to location of the slide
Cloning of live slide view
  • Simultaneous live review of multiple regions of the same slide
For second-opinion consultation



Hybrid system with remote review of live or Z-scanned images                                                                    
  • Review live slides or scanned images in several planes
User can pass control to and regain control from any remote user
  • You or your consultant can drive and review the case, enabling a true interactive consult
Remote access to slides
  • Perform a second-opinion consult on the same day, eliminating delays and slide shipment and associated costs
Simultaneous viewing and control of up to 4 slides
  • You can compare live multiple slides at their best focal plane (IH + ISH consults)
