Optical Microscopy provides detailed visual examination of materials, surfaces, and defects at magnifications ideal for assessing morphology, particle size, surface features, and early‑stage failures. Using both brightfield and polarized light techniques, we evaluate contaminants, inclusions, coatings, and structural irregularities to support characterization, comparison, and quality assessments across a wide range of materials. This method offers fast, reliable insight into visible‑level characteristics that often guide deeper analytical testing.
