About this instrument

Specification		Ultra high resolution	High resolution
TEM resolution (at 200 kV)	Point resolution Lattice resolution Information limit	0.19 nm 0.1 nm ≦0.11 nm (with Cold FEG) ≦0.12 nm (with Schottky FEG)	0.23 nm 0.1 nm ≦0.11 nm (with Cold FEG) ≦0.12 nm (with Schottky FEG)

Cold Field Emission Gun (CFEG):   Provides high brightness and narrow energy spread, enabling high-resolution imaging and precise electron energy loss spectroscopy (EELS) with energy resolution better

than 0.33 eV

Quad-Lens Condenser System:   Independently controls the electron beam intensity (spot size) and convergence angle, providing versatility for various imaging and analytical techniques.

Accelerating voltage

20 kV～200 kV
(200 kV, 80 kV are selectable as a default. Other accelerating voltages are options.)
