fib-o-mat is a toolbox to generate patterns for focused ion beam instruments.

Project description

fibomat logo

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

Pattern geometries can be modeled directly in Python bsaed on (pre-)defined geometric primitives or importet 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 for different microscopes, custom geometric primitives or optimization routines is a straightforward process.

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


Made with :black_heart: and :coffee: at HZB and FBH in Berlin.

Run in a terminal

$ pip install fibomat

It is highly recommended to use virtual environments.


from fibomat import Sample, Mill, Q_, U_
from fibomat.shapes import Line
from fibomat import raster_styles
from fibomat.default_backends import SpotListBackend

# create a Sample class object with optional description
sample = Sample('Useful description here')

# add a site to the sample with cente = (0, 0) and field of view of (10, 10)
site = sample.create_site(dim_position=([0, 0], U_('µm')), dim_fov=([10, 10], U_('µm')))  # '%*µm*)'

# create a Pattern with a Line shape and add it to the site
    dim_shape=(Line((-5, 0), (5, 0)), U_('µm')),
    shape_mill=Mill(dwell_time=Q_('5 ms'), repeats=1),
    raster_style=raster_styles.one_d.Linear(pitch=Q_('1 nm'))

# export a rasterized version of the pattern as text file in a pre-defined (but editable) format. See docs for details.

# plot the pattern
