About

Roughness

Read full description

When it comes to the surface of workpieces, a large number of surface parameters are required in design and manufacture. Before installation or delivery, the workpieces are also verified in quality management. The roughness app from ZEISS provides information on the most common surface parameters with related formulas and graphs.

Materials Lab

Features
Read full description

ZenSee Materials Lab is an interactive visualization workspace for materials science and engineering. The first release focuses on CrystalLab, a lightweight 3D crystal structure viewer for learning, teaching, and report graphics. Choose common crystal structures, inspect unit cells and atoms, rotate the model smoothly, review key structural parameters, and export clean PNG images for slides or notes. Current features: - Simple cubic, body-centered cubic, face-centered cubic, and hexagonal close-packed structures. - Classic teaching examples including diamond cubic, rock salt, cesium chloride, and perovskite structures. - Point-defect examples for vacancy, substitutional, and interstitial defects. - Interactive 3D viewport with rotation, zoom, pan, and mobile-friendly control locking. - Unit-cell frame, atom spheres, Miller guide lines, and neighbor-bond display options. - XYZ and CIF import for simple structure previews. - PNG export for teaching materials, reports, and classroom notes. - Local-first experience with no account requirement. ZenSee Materials Lab is designed for students, teachers, and engineering learners who need a professional, focused way to understand and communicate crystal structures. It is not a finite-element solver, molecular dynamics engine, molecular dynamics production tool, or certified engineering simulation package.
