Non-contact optical measurement
Measure delicate or visual features without touching the part surface.
PKL / PRECISION MEASUREMENT
High-Speed Video Measuring Machines for Production Inspection
PKL helps manufacturers select the right VMM system for fast, accurate, non-contact measurement of small, thin, flat, plastic, rubber, electronic, PCB, glass, and precision components.
VMM / MEASUREMENT IN MOTION
Application-led inspection.
01 / PKL
What is a VMM?
A Video Measuring Machine is a non-contact optical measuring system used for fast dimensional inspection, profile measurement, and repeatable quality control.
Fast batch inspection
Support repeated dimensional checks for production lots and QC sampling.
Ideal for small, thin, flat, and visual-feature parts
Useful for profiles, edges, holes, contours, transparent parts, and fine details.
02 / PKL
When VMM is the Right Choice
Use VMM when the part can be inspected optically and production speed, repeatability, and non-contact measurement matter.
Rubber seals and O-rings
Fast profile and diameter checks for flexible circular parts.
Plastic injection parts
Measure edges, holes, flash, gates, and molded visual features.
PCB and electronics
Inspect board features, pads, connectors, spacing, and small details.
Glass and transparent parts
Optical inspection support for thin, clear, and reflective components.
Small machined components
Check compact turned, milled, punched, and precision metal parts.
Medical and precision components
Repeatable inspection for small devices, microfluidics, and tight-feature parts.

Recommended VMM Families
PKL helps match the VMM model to part size, tolerance, material, and inspection workflow — without over-specifying unnecessary technical data.
VMG Series
High-performance VMM platform for production inspection and advanced application needs. PKL can review VMG 452 and above when the part or fixture requires larger-size capability.
VMQ Series
Large-format VMM solution for bigger parts and applications where a standard VMM measuring range is not enough. PKL can discuss VMQ452, VMQ682, and VMQ8102 based on part size and workflow.

O-Ring / Seal Measurement
Optical profile and diameter checks for rubber seals and flexible circular parts.
Gear Measurement
Fast visual dimensional checks for teeth, pitch, diameter, and profiles.
Thread Measurement
Inspect thread form, pitch, diameter, and critical quality dimensions.
Shaft Measurement
Support optical checks for length, diameter, runout-related features, and edges.
PCB Measurement
Inspect board features, pads, connectors, and electronic component spacing.
Wafer / Semiconductor
Support fine-feature inspection for wafer, semiconductor, and micro parts.
Plastic Injection
Measure molded profiles, holes, edges, flash, and gate-related features.
Large Machined Parts
Use larger-format VMM guidance for parts beyond standard optical range.

VMM vs CMM Guidance
Not sure whether optical inspection or contact probing is the better fit? PKL helps define the right path from your real part and inspection workflow.
VMM is suitable for
Fast optical inspection, small and flat parts, visual features, profile measurement, transparent or delicate parts, and batch measurement where repeatability and speed matter.
CMM is suitable for
3D geometry, GD&T, complex machined parts, mold inspection, jig and fixture inspection, and applications that require tactile probing or deeper 3D feature control.
