Apotome 3

Optical sectioning in fluorescence imaging for your widefield microscope

Create optical sections of your fluorescent samples – with structured Illumination, removal of out-of-focus light becomes simple and efficient, allowing you to fully focus on your research. ZEISS Apotome 3 recognizes the magnification and moves the appropriate grid into the beampath. The system then calculates your optical section from a number of images with different grid positions. It’s a totally reliable way to remove out-of-focus light, even in thicker specimens. Yet your system remains just as easy to operate as always. You get images with high contrast in the best possible resolution – simply brilliant optical sections.

  • Brilliant Optical Sections: Apotome 3 comes with three grids of different geometries, giving you the best resolution no matter which magnification you choose.
  • Free Choice of Light Source and Dyes: Apotome 3 adapts to your fluorophores and lights source. So you stay flexible when your experiments evolve in complexity and requirements.
  • More Structural Information: Your created images are improved even more by deconvolution, using a patented algorithm for structured illumination. Better recognize important structures of your examined objects.
