Laboratory of analysis and observation by Optical Microscope (OM)
What is Optical Microscopy (OM)?
Optical microscopy is an observation technique that enables the surface and structure of materials to be examined on a micrometric scale. Using visible light, it offers rapid, non-destructive visualisation of many types of sample.
In the FILAB laboratory, the Optical Microscope analysis technique is used in conjunction with other analytical methods to provide an accurate overview of your materials or defects. In particular, it can be used to identify surface defects, inclusions, areas of wear or corrosion.
We have several optical microscopes at our disposal, including a latest-generation microscope equipped with several modes such as: reflection (light and dark background), transmission, polarisation, cross-polarisation, etc. The instrument is automated and linked to dedicated software.

FAQ
Optical microscopy analysis is a technique used to observe the surface and structure of materials at the micrometric scale using visible light. It allows rapid and non-destructive visualisation of a wide range of samples.
Optical microscopy is used to identify surface defects, inclusions, wear areas, corrosion, microcracks and contaminants. It is widely applied in quality control, failure analysis and expert investigations.
Optical microscopy analysis can be applied to metals, polymers, powders, coatings, medical devices and composite materials.
Optical microscopy offers fast analysis, minimal sample preparation and non-destructive observation. It provides a global overview of materials before more advanced techniques such as SEM or chemical analysis.
Optical microscopy uses visible light and provides micrometric resolution, while scanning electron microscopy (SEM) uses electrons to achieve nanometric resolution. Optical microscopy is often used as a first-line investigation tool.
Yes, optical microscopy is frequently combined with SEM, thermal analysis, X-ray techniques or chemical analysis to provide comprehensive material characterization.
FILAB offers multidisciplinary expertise, state-of-the-art optical microscopy equipment and COFRAC ISO 17025 accreditation, ensuring reliable and fully interpreted analytical results.
