When precision matters, few techniques match the power and reliability of interferometry. Used to measure surface flatness, texture, and thickness at the nanometre level, this non-contact optical method is widely trusted across sectors such as aerospace, semiconductors, and medical manufacturing.
At Omniscan, we specialise in high-precision metrology solutions – and interferometry is a key part of what makes our inspections both fast and accurate.
Unmatched Accuracy at the Nanometre Scale
Interferometry is capable of detecting surface deviations at the scale of nanometres. This level of precision is crucial for applications where even the slightest variation can lead to functional failure or reduced performance.
Whether it’s an optical lens, a semiconductor wafer, or a mirror used in aerospace navigation systems, interferometry provides the clarity and detail required to meet the strictest industry standards.
Non-Contact and Non-Destructive
Unlike traditional stylus-based methods, interferometry does not rely on physical contact with the surface being measured. This makes it the ideal choice for delicate, soft, or highly polished components that could be scratched or altered during contact inspection.
By preserving the integrity of the surface, interferometry supports both production environments and final quality control checks – especially for high-value or precision-critical parts.
Rapid, High-Volume Data Collection
Interferometric systems are exceptionally fast. Entire surface areas can be scanned in seconds, generating 3D surface maps with detailed height information. This allows for quicker decision-making and immediate feedback in both R&D and manufacturing environments.
When integrated into a production process, this speed supports inline inspection, reducing bottlenecks and improving overall efficiency.
Versatile Across Multiple Industries
One of the major strengths of interferometry is its adaptability. It is used in:
- Semiconductor manufacturing – for wafer flatness and defect detection
- Aerospace engineering – for verifying optical mirrors and precision-machined parts
- Medical devices – for inspecting implant surfaces and surgical tools
- Precision optics – for lens curvature and surface uniformity
In every case, surface perfection directly impacts performance, and interferometry provides the confidence that specifications are met.
