Accessoires

A picture is worth a thousand words. But sometimes a picture is not enough. When researchers need other tools and techniques to go beyond nanometer scale imaging, these instruments and products for SEM or TEM are the answer. They allow scientists to measure elemental composition or crystallography, probe valence band transitions, count single electrons in EM images or perform in-situ experiments at unprecedented acquisition rates. We list below instrumentation and equipment meant to be added to or work together with an existing electron microscope.

Cathodoluminescence

 

Cathodoluminescence (CL) is the emission of photons of characteristic wavelengths in the visible spectrum which is caused by the interaction of the electron beam with a sample. CL is a powerful structural and compositional analysis technique for materials that can reveal valuable information that cannot be obtained through SE, BSE or EDX. Such information includes zonal composition, lattice structure, superimposed strain or damage to the structure of the material. SEM-based CL imaging achieves much better resolution compared to optical CL microscopes.

 

NEW Gatan Monarc CL detector dramatically boosts sensitivity and spectral resolution, empowering the most complete CL analysis to date with unique wavelength- and angle-resolved capabilities.  

 

  • Gatan ChromaCL2 Live color cathodoluminescence imaging system
  • Gatan Vulcan cathodoluminescence (light) collection, detection, and analysis system for the (scanning) transmission electron microscope


Cameras: CCD and direct detection

 

CCD or CMOS based digital cameras to acquire images in Transmission Electron Microscopy. From entry-level devices to the latest in-situ direct detection technology.

 

  • Gatan K3 next generation direct detection camera optimized for the most demanding low-dose applications in both life science and materials science
  • Gatan K3 IS the world's first counting, high-speed, large format camera for in-situ microscopy
  • Gatan OneView 4k x 4k CCD camera
  • Gatan Rio CMOS camera with high resolution, speed, and ease of use


Chillers

 

Chillers and heat exchangers to cool equipment and keep them at a stable working temperature, to ensure optimal performance and minimize thermal drift.

 


Electron Energy-Loss Spectrometers (EELS) and Gatan Imaging Filters (GIF)

 

By measuring the energy lost by the electron beam in its interaction with the sample it is possible to obtain chemical and elemental information with high energy resolution. It is also possible to filter electrons based on their energy loss and thus create an elemental map or improve image quality by removing inelastically scattered electrons.

 

  • Gatan Enfinium dedicated, hard-working spectrometers for EELS experiments
  • Gatan GIF Quantum high throughput spectrometers to capture highly detailed data from EELS and EFTEM experiments
  • Gatan GIF Quantum LS system with high resolution and contrast for cryo-EM by combining low distortion GIF Quantum optics with a K2 Summit detector


SEM or FIB miscellaneous accessories

 

The beams in a SEM or FIB are capable of producing a variety of signals (SE, BSE, SI, etc.), which can be acquired by special detectors as listed below. We also list other accessories to help SEMs experiments, such as decontaminators, flood guns, and devices not listed in the other categories.

  • ORS Dragonfly 3 a software platform for the intuitive inspection of multi-scale multi-modality image data


STEM detectors

 

Scanning Transmission Electron Microscopy is a combination of SEM and TEM in which the beam is raster-scanned over the sample and the transmitted electrons are collected by a detector underneath. It can be used in SEMs or TEMs provided the samples are thin enough. Depending on the collection angle of the transmitted electron, we distinguish between Bright Field (BF), Dark Field (DF) and High Angle Annular Dark Field (HAADF) detectors.

 

  • Gatan Advanced STEM detectors HAADF, annular dark field (ADF) plus bright and dark field (BF/DF) detectors for STEM imaging optimized for EELS

This laser-based technology enables researchers to see the dynamics of nanomaterials at fast time scales and with high throughput. These products capture images at the ultrafast time scales that are essential to our understanding of many important nanomaterials, including proteins, drug encapsulation nanoparticles, catalyst nanoparticles, thin films, photonic waveguides, optical metamaterials and semiconductor devices. We believe that by illuminating the dynamics of the nanoscale, our products will drive technological and scientific progress across a host of markets and disciplines.
