🔹 Description

Rectangular mesh TEM grids feature elongated openings arranged in a rectangular pattern, providing a larger viewing area compared to standard square mesh grids.

The design reduces the number of grid bars in the field of view while maintaining sufficient mechanical support for the specimen.

🔹 Specifications

🔹 Mesh Structure

Rectangular mesh is typically defined by two mesh values:

• Long direction (e.g., 300)
• Short direction (e.g., 75)

This creates elongated openings with increased open area compared to square mesh.

🔹 Key Features

• Rectangular mesh structure with elongated openings
• Larger open viewing area than square mesh
• Reduced grid bar interference in imaging
• Maintains good mechanical stability
• Suitable for alignment with tilt axis in tomography

🔹 Applications

• TEM imaging requiring larger observation area
• Electron tomography (aligned with tilt axis)
• Nanomaterial and thin film analysis
• Applications requiring reduced grid shadow
