GBI Upgrades

In the 1990s the NPL-Tesa Automatic Gauge Block Interferometer (AGI) was the instrument that set much of the World’s measurement standards. Now B&S has introduced the GBI300, an improved version of the GBI resulting from recent developments at NPL. If you have one of the 20 or more NPL-Tesa AGI100 or AGI300 GBI’s you can now get an upgrade to the full GBI300 specification.

  • FLaP for Windows™ software
  • Phase stepping optical system
  • Improved measurement of Flatness and Length Variation
  • Improved ease of use
