Smart Imaging Without Limits

The VX3 Stereo Microscope and 4K Autofocus Digital System deliver powerful macro imaging for industrial and metallographic applications. The VX3 offers optical stereo zoom with true 3D depth perception and repeatable magnification, ideal for hands-on inspection. The 4K Autofocus provides ultra-high-definition digital imaging with autofocus, an expansive field of view, and built-in measurement tools—perfect for fast documentation and multi-user environments.

Together, they offer flexible solutions for surface analysis, failure investigation, and quality control.

Hassle-Free Focus & Lighting

Continuous auto-focus and auto-exposure mean no more manual focusing or constant light adjustments to get a clear image. Uneven or 3D surfaces come out sharp using the focus-stacking capability—no more blurry areas on rough samples.

Large Sample Accommodation

The days of saying “my sample is too large for the microscope” are over.

With an expansive stage view and removable camera, the 4K microscope handles large, heavy, or odd-shaped samples that standard microscopes and competitors struggle with. This expands analytical opportunities for parts that previously required sectioning or special setups.

All-in-One Imaging & Measurement

Because the 4K microscope has PC-grade processing and software built in, you don’t need a separate computer or multiple devices to capture images, annotate, and measure. This simplifies the workflow and reduces data transfer errors, allowing you to go from analyzing to saving results on a single platform. Consistent calibration with a pre-calibrated HDMI output for measurements ensures reproducible results across different operators and sessions.

Minimal Consumables or Maintenance 

The system is purely digital-optical, so no consumable reagents or gases are required to operate. Unlike an electron microscope, there’s no vacuum system or special sample coating needed—just place your sample and observe. The long-life LED illumination and lack of moving optical parts make the 4K microscope extremely low-maintenance and reliable for long-term use.


Zoom in on the LECO VX3 Stereo Microscope

Versatile Stereo Optics

Offers a 6.7:1 zoom ratio for detailed 3D imaging at various magnifications, making it ideal for close-up inspections of macro features. The stereo view provides depth perception, which is crucial for examining surface topography (e.g. fractures or tooling marks).

Repeatable Magnification Settings

Integrated click-stop detents ensure you can return to set magnifications precisely. This repeatability improves measurement consistency.  For example, you can compare grain sizes or defect dimensions under the same zoom level on different days.

Simultaneous Viewing & Imaging

The VX3’s optical head uses a permanent light splitter that sends imagery to both the eyepieces and an attached camera simultaneously. This means you can capture photos or video without flipping levers or disrupting your vision through the eyepieces, streamlining documentation, and demonstrations.

Robust Ergonomic Design 

A 25-inch boom stand with a horizontal slider provides a wide range of motion, allowing you to maneuver the microscope over large or oddly shaped samples. The sturdy stand and focus mechanism are built for durability and stability, ensuring clear images even when working with heavy parts.

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.
