Continuous Focus and Optimized Imaging
The 4K Digital Microscope simplifies image capture with continuous autofocus and auto-exposure technology that automatically maintains image clarity and proper lighting conditions. Advanced focus-stacking capabilities bring uneven, textured, and three-dimensional surfaces into sharp focus, producing clear, detailed images across the entire sample. By eliminating manual adjustments, users can achieve high-quality results faster and with greater consistency.

Large Sample Accommodation
Designed to overcome the size limitations of traditional microscopes, the 4K Digital Microscope is well suited for large, heavy, or irregularly shaped samples. Its expansive viewing area and removable camera provide the flexibility to inspect parts that may be difficult or impossible to evaluate using conventional microscopy systems. This expanded sample capacity opens new analytical opportunities while reducing the need for sectioning, repositioning, or specialized fixturing.

Integrated Imaging, Analysis, and Measurement
With powerful onboard processing and integrated software, the 4K Digital Microscope combines image capture, annotation, measurement, and data management within a single platform. Eliminating the need for an external computer simplifies workflow, reduces complexity, and minimizes the risk of data transfer errors. Users can move seamlessly from inspection and analysis to reporting and documentation, improving efficiency and productivity throughout the imaging process.

Advanced Stereo Imaging Performance
The VX3 delivers detailed three-dimensional imaging through a powerful 6.7:1 zoom ratio, providing the flexibility to examine samples at a wide range of magnifications. True stereo optics create natural depth perception, making it easier to evaluate surface features such as fractures, wear patterns, tooling marks, and other topographical characteristics. This combination of magnification flexibility and depth awareness supports confident analysis across a variety of inspection applications.

Repeatable Magnification for Consistent Analysis
IIntegrated click-stop zoom positions allow users to return to predefined magnification settings with confidence and precision. This repeatability helps standardize inspections, improve measurement consistency, and ensure reliable comparisons between samples over time. Whether evaluating welds, defect dimensions, or surface features, users can achieve more consistent and reproducible results.

Simultaneous Viewing and Digital Imaging
An integrated light splitter delivers images to both the eyepieces and an attached camera at the same time, eliminating the need to switch between viewing and image capture modes. Users can seamlessly capture photos or video while maintaining continuous visual observation, streamlining documentation, collaboration, training, and reporting workflows.

Ergonomic Design for Large Sample Inspection
The VX3 can be equipped with a robust 25-inch boom stand and horizontal slider that provide exceptional positioning flexibility for large, heavy, or irregularly shaped samples. Its durable construction and stable focusing mechanism help maintain image clarity during inspection, while the expanded range of motion allows users to easily evaluate challenging specimens without repositioning the sample. The result is a comfortable, efficient inspection experience and reliable imaging performance across a broad range of applications.

How LECO Macro Inspection Microscopes Work
LECO’s macro inspection solutions combine the strengths of both optical and digital microscopy to provide unmatched clarity, flexibility, and ease of use for surface evaluation. The VX3 Stereo Microscope delivers true optical depth perception and hands-on sample interaction, while the 4K Autofocus Digital Microscope offers fast, high-resolution imaging and effortless documentation. Together, they provide a complementary toolkit for quality control, failure analysis, and detailed surface characterization across a wide range of materials.
The VX3 Stereo Microscope uses a dual optical path to generate a true 3D stereoscopic view through its eyepieces, giving users exceptional depth perception for hands‑on inspection. Its 6.7:1 zoom ratio with click‑stop detents ensures repeatable, precise magnification adjustments, while the lengthy working distance accommodates larger or irregularly shaped samples. Designed for comfort and flexibility, the VX3 provides clear, natural visualization for surface assessment, rework, and detailed macro inspection tasks.
The 4K AutoFocus Digital Microscope is a complete digital imaging system that pairs a high‑resolution 4K camera with an electronic zoom lens to deliver crisp, real‑time images directly to a monitor. Continuous auto-focus and auto‑exposure simplify operation by maintaining sharpness and lighting without manual adjustments, and the integrated LED ring light ensures even illumination across the field of view. Onboard software supports measurement, annotation, and image capture, making the system ideal for rapid documentation, collaboration, and repeatable analysis.
