fib-o-mat is a Python library to create beam patterns for focused ion beam instruments.

Features:

  • build-in modeling of patterning geometries

  • customizable rasterization styles

  • optimization of patterning geometries and rasterized patterns

  • extendable

Pattern geometries can be modeled directly in Python based on (pre-)defined geometric primitives or imported from vector graphics. These can be equipped with beam and rasterizing settings and exported to microscope compatible files.

fib-o-mat is by designed flexible and easily expandable. Hence, adding support for different microscopes, custom geometric primitives or optimization routines is a straightforward process.

For the usage of fib-o-mat, basic python knowledge and good understanding of the target microscope are mandatory. See Getting started for an introduction to this library and the User Guide for a complete documentation. The module reference is to be found here.

Please use the issue system on gitlab for bug reports and questions concerning the package.

Made with 🖤 and ☕ at HZB and FBH in Berlin.
