    Features

    Ultra High Resolution Imaging; 1 nm/15 kV, 1.6 nm/1 kV (with Beam Deceleration Moda)*

    Ultra high resolution performance made possible with Hitachi's patented semi-in-lens optical design and electron gun technology.

    In-lens SE and BSE Signal Filtering and Mixing Mode

    Enables SE and BSE signal collection and control to eliminate or reduce specimen charging and enhance compositional contrast information.

    Sub Nanometer Level Surface Observation at Ultra Low Accelerating Voltages

    Provides high resolution, sub nanometer level surface observation at ultra-low accelerating voltages down to 100 V by utilizing the electron beam deceleration function.

    Maximum Probe Current of 100 nA or Greater Available with the Field Proven Schottky Electron Source

    High current and high resolution conditions are optimized for analytical techniques such as EDS*, WDS*, EBSP*, CL*, and e-Beam lithography* for increased productivity and throughput.

    EBSP Analysis In Field Free (FF) Mode

    Hitachi's unique FF mode eliminates the projected magnetic field of the objective lens associated with semi-in-lens technology, and thereby eliminates artifacts during analysis of magnetic samples and with EBSP* applications.

    Large Analytical Specimen Chamber

    Designed to optimize the simultaneous analysis of a wide variety of analytical techniques such as EDS*, WDS*, EBSP*, CL* and e-Beam Lithography* by optimizing the analytical detector solid angle and maintaining high resolution.
