Monarc Pro T System for Optically-Coupled TEM

The Monarc® Pro T from Gatan is an advanced system for optically coupled transmission electron microscopy (TEM). Using this device, users can unveil the structural, optical, and electronic attributes of materials beyond the optical diffraction boundary.


  • Turns any microscope into an optically-coupled microscope, allowing for in-situ discovery of photoactive catalyst reactions: Ensures consistent illumination over a 150 μm field of view with an optical system integrated into a TEM holder.
  • Delivers the sharpest cathodoluminescence (CL) images and spectra: Uses proprietary mirrors (solid angle up to 7.3 Sr) for outstanding light collection, producing spectra with sub-meV energy resolution with an aberration-corrected spectrograph.
  • Simplifies the workflow for multimodal analysis: Uses eaSI technology to deliver the most efficient and effective workflow for your advanced STEM experiments.
