Precision Measurement for Manufacturing Excellence
Non-contact dimensional measurement with micron-level accuracy
Optical metrology enables fast, non-contact measurement of dimensions, surfaces, and shapes. From inline gauging on production lines to lab-based CMM alternatives, machine vision and 3D sensors provide the speed and accuracy modern manufacturing demands. Unlike contact methods, optical systems don't deform soft materials or wear over time.
Key Use Cases
Inline Dimensional Gauging
Measure critical dimensions on every part at production speed. Detect trends and variations before they become defects.
Surface Profiling
Capture 3D surface profiles for flatness, roughness, and form measurement without physical contact.
Gap and Flush Measurement
Measure gaps between panels and alignment of surfaces—critical for automotive body-in-white and consumer electronics.
Thread and Fastener Inspection
Verify thread pitch, depth, and profile to ensure proper assembly and prevent field failures.
Enabling Technologies
3D Laser Profilers
High-speed, high-accuracy profile measurement using laser triangulation
Structured Light
Full-surface 3D capture for complex geometries
Telecentric Lenses
Eliminate perspective distortion for accurate 2D measurement
Lightfield Cameras
Sub-pixel accuracy for dimensional inspection
Customer Pain
Manufacturers increasingly need tighter tolerances and higher throughput but traditional measurement approaches struggle to keep up.
- •Slow, sample-based measurement that misses variation across production
- •Contact methods that deform soft parts or wear over time
- •Manual or lab-based inspection that disconnects measurement from the process
- •Limited visibility into process drift, leading to scrap or rework
- •Bottlenecks caused by CMMs, especially in high-mix production
As tolerances tighten and production speeds increase, these limitations directly impact quality and yield.
Our Solution
We support customers using optical metrology systems that deliver accurate, repeatable measurement without physical contact. By combining high-resolution imaging, 3D sensing, and precision optics, these systems can measure critical dimensions on every part, not just samples, operate inline at production speed, capture full-field surface and geometry data, detect trends and variation early, before defects occur, and integrate measurement directly into manufacturing workflows.
By combining vision and metrology in one architecture, automation becomes simpler, more robust, and easier to scale:
- •Measure critical dimensions on every part, not just samples
- •Operate inline at production speed
- •Capture full-field surface and geometry data
- •Detect trends and variation early, before defects occur
- •Integrate measurement directly into manufacturing workflows
- •Faster feedback, reduced scrap, and greater confidence in process capability
