Huygens Chromatic Aberration Corrector

Correct xyz shifts, rotations, and scaling and radial differences between channels

Nearly all multi-channel images show some degree of chromatic aberration. Chromatic aberration appears as focal shifts and possible scaling, rotational, and radial (2nd, 4th, 6th degree) distortions between fluorescent channels. In addition, misalignment between light paths during acquisition can result in lateral (xy-direction) shifts between channels. These aberrations clearly affect any type of multi-channel analyses like colocalization and object-based analysis, and should therefore be fixed beforehand. The versatile Huygens Chromatic Aberration Corrector includes an easy-to-use Wizard that accurately estimates, visualizes and corrects all these chromatic aberrations. For any additional crosstalk/bleed-through in your multi-channel data, you can have a look at the Huygens Crosstalk Corrector as well.

Easy-to-use Wizard

Apply automated estimation and correction with just a few mouse button clicks.

Accurate and complete

Visually inspect the estimated distortions using the orthoslicer and interactive 3D wireframe MIP.

Batch correction

Save correction templates for replicability and batch processing in the Workflow Processor.


The deconvolution and chromatic aberration corrector have improved our bead representation. Chromatic shift was a problem with our objective but now it seems much reduced, so we are happy.

I have been a Huygens user for 8-9 years now and the support provided by you guys are fantastic!

Reliable analysis

Chromatic aberration significantly influences the results of multichannel analysis like colocalization, or distance measurements as part of object-based analysis. Huygens Chromatic Aberration Corrector offers an easy-to-use wizard to correct for serveral types of distortions.

Broad set of distortions corrected

Huygens Chromatic Aberration Corrector Wizard helps you with selecting the right set of corrections to address misalignments (shifts), scaling and rotational differences, and radial (2nd, 4th, 6th degree) distortions between channels. Radial deformations are caused by optical aberrations and appear as a pincushion or barrel distortion, or as a combination of both, also known as mustache distortion.

Besides a 3D shift between channels, shown within this axial view of a SFP-rendered 4-channel TetraSpeck® bead (Thermo Fisher Scientific), your image may also suffer from other distortions. These distortions are visualized as a 3D rendered wireframe by the Wizard. Example wireframes (top views) show typical distortions found within microscopy data.

Multi-channel images often suffer from crosstalk (a.k.a. bleed-through), which should be corrected before performing analyses. Huygens offers a wide range of analysis options, for example the assessment of the colocalization between different molecules.

Chromatic Aberration

Recording Beads is a good method to calibrate the existing chromatic aberration. The result of the analysis and correction delivered by the Chromatic Aberration Corrector on a beads image can easily be saved to a template and applied to any image taken under similar conditions. Left: MIP rendered projection of a Huygens deconvolved 3D widefield stack of 100nm 4-channel multicoloured beads (TetraSpeck - Life Technologies). Chromatic Aberration between channels can be more clearly measured and corrected after deconvolution. Right: MIP projection of the same image after using the Huygens Chromatic Aberration Corrector. Insets show a larger view of a single XZ slice of one bead.
