Cold field emission gun (Cold FEG)
Cold FEG produces a high-brightness electron beam with very small energy spread, offering high coherency. Thus, the CRYO ARM™ 200 achieves high resolution, high contrast imaging.
Incolumn energy filter (omega filter)
Equipped with an incolumn energy filter (omega filter), the CRYO ARM™ 200 acquires energy filtered images and energy loss spectra. Zero-loss image acquired with the microscope provides high contrast with reduced chromatic aberration.
Automated specimen exchange system
The system is composed of a specimen stage to cool samples at liquid nitrogen temperature and a cryo-transfer system to automatically transfer the cooled samples to the cryo-stage. Liquid nitrogen is automatically supplied to the liquid nitrogen tank as required. This automated system features the storing of up to 12 samples and the exchange of arbitrary one or more samples while the rest of samples are kept cooled between the specimen stage and specimen exchange system. These unique capabilities enable flexible scheduling of microscopy.
