Microscopy Solution

Innovative and Intuitive Super Resolution Microscopy Solution

Founded in 2010 and located in Paris, BioAxial is a key player in live cell super resolution microscopy. Our company develops and sells super resolution modules: LiveCodim, using Conical Diffraction, an outstanding technology for super-resolved fluorescence microscopy for extended live-cell imaging.

2019 BioAxial became a part of Telight.


Conical diffraction can be used as a practical tool to shape optical beams. In 2006, Gabriel Sirat created a versatile beam shaper and applied it to super resolution fluorescence microscopy. A thin biaxial crystal transforms the Point Spread Function (PSF) of a regular incident beam into an extensive family of light distributions, the choice of the distribution being controlled by the input and output polarizations.

Practically, beam shaping is achieved by enclosing the biaxial crystal between controllable polarizers; this simple optical set-up, similar to a polarimeter, has the ability to switch from one pattern to another pattern with a different topology in microseconds – or even faster. In addition, these patterns are perfectly colocalized, as they produced by the same primary optical beam.

Telight LiveCodim

From conventional to super-resolution microscopy

LiveCodim is a universal, super-resolution imaging platform, designed to interface with any standard fluorescence microscope. It is the solution for live imaging with high resolution and low phototoxicity.

Horizon 2020

BioAxial’s LiveCodim has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No. 811988 – LiveCodim.
