High-Resolution Imaging
See Your Materials Like Never Before

High-resolution imaging through Scanning Electron Microscopy (SEM) gives you the ability to visualize the incredibly fine details of a sample’s surface topography. Our SEM equipment has both a Backscattered Electron Detector (BSD) and a Secondary Electron Detector (SED), which can be configured to readily identify different phases present in a sample and provide crisp and high-resolution surface-sensitive imaging. This level of detail allows for:
- Observation of nanoscale features: Revealing structures, defects, and particles that are invisible to traditional microscopes.
- Precise measurements: Determining the size, shape, and distribution of nanoscale components with high accuracy.
- Detailed surface characterization: Understanding the surface roughness, texture, and topography of materials.
Materials Science Applications include:
- Battery: High-resolution imaging of battery materials offers invaluable insights for optimizing performance, longevity, and safety. By visualizing the material’s microstructure, researchers and engineers can understand degradation mechanisms, optimize material design, improve quality control, and even accelerate battery development.
- Coatings: SEM offers a wealth of information crucial for the coatings industry. By visualizing the coating’s microstructure at the nanoscale, manufacturers can accelerate coating development by analyzing failure modes to improve quality control and optimize coating performance.
Available Magnifications:
Our SEM can obtain images up to 100,000 times magnification and resolution smaller than 10 nm.
SEM Elemental Analysis
Unveiling the Composition of Matter
SEM elemental analysis is a powerful technique that combines Scanning Electron Microscopy (SEM) with Energy Dispersive X-ray Spectroscopy (EDS) to determine the elemental composition of a sample. This method offers valuable insights into the distribution and concentration of elements within a material.
How it works:
- SEM Imaging: The SEM generates high-resolution images of the sample’s surface, allowing for the identification of specific areas of interest for elemental analysis.
- EDS Analysis: The EDS detector captures the characteristic X-rays emitted by the sample when bombarded with the electron beam. These X-rays correspond to the elements present in the sample.
- Data Interpretation: The EDS spectrum provides information about the elements present, their relative concentrations, and their spatial distribution within the analyzed area.

Benefits of SEM Elemental Analysis:
- High spatial resolution: Allows for the analysis of small features and inclusions.
- Non-destructive: Does not damage the sample, enabling further analysis.
- Rapid analysis: Provides quick elemental information without extensive sample preparation.
- Versatility: Applicable to a wide range of materials, including metals, ceramics, polymers, and composites.
By combining imaging and elemental analysis, SEM-EDS is an invaluable tool for researchers, engineers, and scientists across various industries.
EDS Image Samples
Elemental Analysis Example
Elemental composition analysis can be obtained from several chosen spots of your sample through Energy Dispersive Spectroscopy (EDS). 
Elemental Mapping Example
We can also obtain elemental information throughout the distribution of the whole sample via Energy Dispersive Spectroscopy (EDS) Mapping.
