Beyond digital pathology scanner

We design and manufacture scanners to meet the needs of diverse application scenarios.

From 5 to 400 slides

our five throughput models are built for any workload scenario. Engineered for precise, automated scanning of all slide types, they seamlessly adapt their mode to the task. Coupled with a complete software suite, they transform scanned data into actionable insights—streamlining storage, management, diagnostics, research, and analysis.

True-to-Life Color, Built on Precision.

Our scanners deliver unmatched color fidelity through Independent Three-Channel Processing and the proprietary K-SCP (Specialized Color Processing) engine. This integrated system systematically enhances color, saturation, white balance, and contrast for exceptional image accuracy.

With built-in ICC profile calibration, colors remain consistent and reliable across all displays. From precise capture to faithful presentation, every digital slide is rendered perfectly trustworthy.

Unrivaled Optics, Unmatched Clarity.

We achieve a dramatic leap in optical resolution through holistic optimization of the entire imaging chain—from the light source and objectives to the camera and optical pathway. This premium configuration reveals exquisite cellular details, delivering images with razor-sharp nuclear edges and crisply defined internal architecture.

Core technology

Precision engineering, from optics to motion

Every KF-PRO scanner is a tightly integrated opto-mechatronic instrument, built to capture vast amounts of microscopic data at speed without compromising image quality.

Maglev Linear-Motor Drive

The same magnetic-suspension linear motor used in semiconductor lithography, paired with optical-grating closed-loop position feedback. High thrust, non-contact and frictionless for silent, ultra-stable scanning with positioning accuracy down to the nanometre scale.

Tri-Linear Line-Scan Camera

Three independent sensors capture R, G and B separately with no cross-channel interference, reducing chromatic aberration for true-to-life colour. 4K pixels at a 7.5µm pitch and up to 10 Gbps deliver richer detail with seamless, seam-free stitching.

Apochromatic X-Line Optics

Evident (Olympus) X-Line UPLXAPO 20× NA 0.8 apochromatic objective — flat field, corrected chromatic aberration — reveals crisp nuclear edges and clearly defined internal structure. Optional 40× NA 0.95 for the highest magnification needs.

High-Precision Autofocus

Automatic focus across a 0.25µm depth of field keeps every field sharp, while Z-stack scanning (up to 10 layers) with multi-layer image fusion captures thick and cytology specimens in full three-dimensional clarity.

Grows with your lab

Field-upgradeable fluorescence

Every model except the KF-PRO-040 can be upgraded to fluorescence scanning on the existing instrument — no replacement required. Add an sCMOS camera and a Lumencor-class light engine to unlock 3 to 10 configurable channels with KF-DAPI, GREEN, ORANGE, RED, CY5 and CY7 filter sets.

Data you can use anywhere

Supported image & file formats

KF-PRO scanners output open, widely adopted formats for both brightfield and fluorescence, so your digital slides integrate smoothly with viewers, storage and analysis tools.

KFB & KFBF

KFBIO native formats — KFB for brightfield and KFBF for fluorescence — optimised for fast pyramidal viewing in the KFBIO software suite.

SVS

Aperio-compatible tiled pyramid format, widely supported across third-party viewers, image-analysis tools and AI pipelines.

TIFF / QPTIFF

Universal tiled pyramidal TIFF for brightfield, and QPTIFF for multi-channel fluorescence with preserved channel metadata.

DICOM (WG26)

Standards-based DICOM whole-slide imaging for seamless integration with PACS, LIS and hospital information systems.

Open interoperability

Export the same scan to multiple formats so data flows freely between clinical, research and archival systems without vendor lock-in.

AI & analysis ready

Formats chosen for direct compatibility with common deep-learning frameworks and quantitative pathology software.

Fully compatible with the WG26 digital pathology DICOM file format

This comprehensive compatibility ensures that KFBIO scanners can seamlessly generate, process, and exchange DICOM-compliant digital pathology images, enabling smooth integration with hospital information systems, pathology databases, and other medical devices for enhanced interoperability in clinical and research workflows.The DICOM digital pathology format is a specialized extension of the DICOM (Digital Imaging and Communications in Medicine) standard, designed specifically for pathology imaging. It standardizes the storage, transmission, and management of whole slide images (WSI) and associated data, such as annotations, metadata, and clinical information. By providing a consistent framework, this format facilitates reliable data exchange across different platforms and vendors, supporting key applications in telepathology, artificial intelligence analysis, and long-term archival. It promotes efficiency, accuracy, and collaboration in modern digital pathology practices.

Frequently asked questions

The series spans five throughput levels — KF-PRO-005, -020, -040, -120 and -400 — with slide capacities of 5, 20, 40, 120 and 400 slides respectively. This lets you match the instrument to anything from a single-slide desktop workflow to a fully automated high-volume laboratory.

In brightfield at 20× the KF-PRO Series scans a 15×15 mm region in about 15 seconds per slide, reaching up to 72 slides per hour at 20×. Speed depends on the scan area, focus points and magnification selected.

Scanning resolution is 0.25 µm/pixel at 20× and 0.125 µm/pixel at 40×, using an Evident (Olympus) X-Line UPLXAPO 20× apochromatic objective at NA 0.8. An optional 40× NA 0.95 objective is available for the highest-magnification needs.

Every model except the brightfield-only KF-PRO-040 can be upgraded to fluorescence on the existing instrument. The fluorescence module supports 3 to 10 configurable channels (KF-DAPI, GREEN, ORANGE, RED, CY5 and CY7 filter sets) using an sCMOS camera and a solid-state light engine.

Brightfield scans are saved as KFB, SVS, TIFF or DICOM, and fluorescence scans as KFBF or QPTIFF. The same scan can be exported to multiple formats so data integrates with viewers, storage, PACS/LIS and AI-analysis tools without vendor lock-in.

Yes. The scanners are fully compatible with the WG26 digital-pathology DICOM standard for whole-slide imaging, enabling reliable exchange with hospital information systems, pathology databases and other medical devices.

Yes. Z-stack scanning captures up to 10 layers with multi-layer image fusion, so thick tissue and cytology preparations are rendered with full three-dimensional clarity across a 1 mm field of view.

Yes. Consistent, high-fidelity output in open formats (SVS, TIFF, DICOM) makes KF-PRO scans a reliable data foundation for AI-assisted diagnosis and quantitative pathology, and they are already trusted by more than 1,500 medical institutions.

Ready for what comes next

A solid foundation for pathology AI

Open, standards-based output (KFB, SVS, TIFF and DICOM WG26) and consistent, high-fidelity imaging make KF-PRO scanners the dependable data source that AI-assisted diagnosis and research are built on — already trusted by more than 1,500 medical institutions.
