The GelSight Benchtop Scanner can quickly capture the surface geometry of almost any material regardless of its optical properties. This capability is due to the GelSight sensor, a small block of elastomer with a reflective coating on one side. The unique properties of the GelSight sensor remove the influence of the optical characteristics of the material on the measurement, thereby ensuring accuracy, repeatability, and consistent performance, even on optically complex surfaces.
SEM-like images: GelSight images are often compared to images from a scanning electron microscope (SEM) because both systems reveal surface structure without being influenced by the surface's optical characteristics. While SEMs offer amazing resolution, they operate in vacuum, require elaborate sample preparation, and typically only capture a small field of view. For imaging at the micron scale and above, GelSight can capture comparable images with much less time and effort.
Fast 3D: Unlike scribe profilometers and other scanning technologies, GelSight 3D scanners capture the entire surface in just a few images. Fast acquisition means no measurement drift, less sensitivity to vibration, no sensitivity to environmental changes (e.g., temperature), and fast, reliable results.
Repeatability: The GelSight sensor removes the influence of the optical properties of the material on the measured geometry. You can expect high-quality, reliable results on almost any material, such as glass, plastic, metal, as well as combinations of materials.
Accuracy: GelSight 3D scanners measure depth to submicron accuracy.
