Optomech VPP Vision Measuring Machines combine high-resolution digital imaging with precision encoder stages to deliver multi-feature dimensional measurement at the speed of a camera. From manual bench-top models to full CNC servo systems, the VPP series scales from single-operator lab use to automated production inspection.
A Vision Measuring Machine (VMM) — also called a Video Measuring Machine or Optical CMM — uses a calibrated digital camera mounted on a precision motorized stage to capture images of a workpiece and extract dimensional data through automated edge detection algorithms. No probing. No contact. No part deflection.
The operator places the part on the stage, the camera traverses to each feature, the software automatically detects the edge, and the system computes the dimension with full tolerance comparison. A complete inspection report is generated at the end of the routine. In CNC mode, the entire sequence runs automatically without operator intervention.
| Situation | Why VMM is Preferred |
|---|---|
| Many features per part | Camera captures entire FOV — measure 20+ dimensions in one image |
| Delicate or soft materials | Zero contact — no deflection, marking, or damage |
| Fine, small features | Camera magnification reveals sub-mm features impossible to probe |
| PCBs and electronics | Flat, reflective parts easily handled on stage |
| Scripted production batches | CNC series runs fully automated inspection programs |
| Mixed parts per shift | Switch part programs in seconds — no fixture changes |
All VPP models share the same measurement philosophy and software ecosystem. Operators trained on the ME series work immediately on the CNC series. Choose the series that matches your automation and accuracy requirements today — and scale up when you need to.
The VPP ME is Optomech's entry-level vision measuring machine. The XY stage is moved manually by the operator using precision handwheels. The camera provides a high-quality live image, and the software's edge detection algorithms measure features automatically once the operator positions the camera over each feature.
The right choice for quality labs that currently use profile projectors or optical comparators and want to step up to automated edge detection and multi-feature measurement — without the cost of a full CNC system. Measurement throughput is operator-dependent but significantly faster than manual instruments.

The VPP MAZ series adds motorized Z axis with autofocus. The operator no longer needs to manually adjust focus when moving between features at different heights — the system maintains focus automatically. The 1.3MP camera upgrade delivers sharper images and improved edge detection on fine features.
The optional touch probe interface allows the VPP MAZ to measure features not accessible to the camera — deep bores, internal channels, and 3D surfaces — making it a genuine hybrid measurement system. The best-selling series in the VPP range, suitable for a diverse range of parts and applications.

The VPP CNC series offers the highest level of automation and accuracy in the standard VPP range. All three axes are driven by Panasonic AC servo motors with 0.1 µm scale resolution. The machine follows a pre-programmed CNC measurement routine without operator intervention — traverse, image, detect, record, report.
Programming uses a simple learn-mode: the operator moves the machine to each feature manually once, the software records the sequence, and the machine runs it automatically from then on. No G-code or CNC programming experience required. The right choice for production SPC programmes, PPAP submissions, and batch inspection.

The VPP CNC HD extends the CNC platform to large-component measurement. With stages up to 600×500 mm, it accommodates large pressed panels, automotive body components, large injection mouldings, and sheet-metal assemblies that cannot fit on the standard CNC stage.
The motorized zoom lens allows the CNC programme to change magnification automatically without manual lens swapping. All illumination channels are programmable within the CNC routine — the machine switches between transmitted, ring, and coaxial light per feature automatically for optimal edge contrast on every part feature.

Consistent illumination is as important as accurate encoders. VPP instruments offer three illumination modes — individually or in combination — to handle diverse surface materials, colours, and textures.
Backlighting through the stage glass creates a sharp, high-contrast shadow silhouette. Ideal for edge measurement of opaque parts — stamped metal, punch profiles, gears, slots, and any part where the external contour is what you're measuring.
LED ring around the lens illuminates the part surface from multiple angles simultaneously. Reduces shadows and highlights surface features — holes, slots, engravings, text markings, and surface geometry not visible in silhouette.
Light projected coaxially through the lens axis reflects directly off flat surfaces back to the camera. Eliminates glare on mirror-finish and lapped surfaces — essential for PCBs, polished metal, and any specular component where ring light causes wash-out.
Windows-based with a touchscreen-friendly interface designed for quality lab operation — not for CAD/CAM specialists. The same software runs across the entire VPP series, so operator training carries across all models.
Points, lines, circles, arcs, ellipses, rectangles, angles, and distances — all measured by automated edge detection algorithms. GD&T evaluations: flatness, straightness, roundness, perpendicularity, concentricity, position, run-out.
Move the machine to each feature once. The software records the sequence. From then on the machine runs the complete programme automatically. No G-code. No CNC experience required.
Automatic dimensional reports to Microsoft Word, Excel, and PDF — with pass/fail status, tolerances, and nominal vs. actual. Real-time SPC charts, Cp/Cpk calculations, and trend monitoring.
DXF import for nominal profile overlay; DXF export of measured profiles for reverse engineering workflows. Separate part programmes per part number with full batch management.
