Optical Microscopy (Light Microscopy)

Our fully motorized Zeiss Axio Imager.Z2 Vario optical microscope enables imaging of both large and thick samples as well as standard small samples. This versatile system supports multiple imaging modes to reveal diverse structural and material features.

What is Optical Microscopy?

Optical microscopy uses visible light and advanced optics to provide fast, non-contact characterization of samples. It is ideal for operando studies, thanks to its open observation area and ability to image through transparent windows.

Capabilities

  • Bright Field Illumination: Classic imaging for general sample observation with both reflection and transmission.
  • Dark Field Imaging: Highlights cracks, edges, and structures in translucent samples.
  • Cross-Polarized Imaging: Reveals anisotropic structures in polymers and oxides.
  • Differential Interference Contrast (DIC): Enhances visibility of subtle topography and refractive index variations.
  • Incident & Transmitted Light Modes: Suitable for opaque and transparent samples.
  • Motorized Control: Automated stage movement and imaging for large samples.

Applications

  • Structural analysis of polymers, composites, and oxides.
  • Crack detection and defect visualization.
  • Operando characterization under controlled environments.
  • Quality control for large or complex samples.
