At Omniscan, we specialise in advanced metrology solutions, including Low Coherence Interferometry (LCI) for ultra-precise surface analysis. Using the cutting-edge OptoFlat system, we can provide accurate, non-contact measurement of flatness and parallelism for high-specification optical and precision glass components.
What is Low Coherence Interferometry?
Low Coherence Interferometry is an optical measurement technique that uses a broadband light source to produce interference patterns only when the optical path difference is within a very short range. This allows it to isolate specific layers or surfaces with micrometre-level accuracy.
Unlike traditional interferometry, which can be affected by environmental vibrations or complex surface geometries, LCI offers high-resolution depth profiling and robustness in real-world conditions—making it ideal for production environments and quality assurance applications.
Why OptoFlat?
The OptoFlat system stands out in the field of low coherence interferometry thanks to its compact design, precision, and ease of use. Developed specifically for the inspection of optical flats, wedges, and transparent materials, OptoFlat offers fast, automated measurements with reliable repeatability.
Key features include:
- High Measurement Accuracy: Micron and sub-micron resolution across a wide area
- Non-Contact Operation: Ideal for sensitive or coated surfaces
- Automated Analysis: Fast, operator-independent results with minimal setup
- Compact and Robust Design: Easily integrates into lab or production environments
Applications Across Precision Industries
OptoFlat is widely used for inspecting:
- Optical flats and reference surfaces
- Beam splitters, filters, and coated optics
- Semiconductor wafers and substrates
- Transparent materials and parallelism of glass components
With increasing demand for high-precision surfaces in optics, photonics, and electronics, LCI provides a trusted method for ensuring flatness and parallelism to the most exacting standards.
