The VEGA3 SBU - EasyProbe is a compact scanning electron microscope (SEM) fully integrated with a selected energy dispersive X-ray microanalyser (EDX). Superior imaging quality, high level of automation, easy usage and quick quantitative elemental results directly in the live image are among the characteristic features of the instrument. A variable pressure vacuum system allows investigation of non-conductive samples in their natural uncoated state.
Key Features of VEGA3 SB - EASYPROBE
- Fully integrated EDX microanalyser for automatic quantitative elemental analysis
- Original EasySEM software interface with One-Touch EDX toolbox
Microscope Control:
The EasySEM control interface is an easy-to-use mode of the main SEM control software. It is optimized for the use with a touchscreen. The EasySEM allows all basic imaging functions and a One-Touch EDX analysis toolbox, both with a great support of background automatics. When the One-Touch EDX tool is activated, the system automatically returns result of a quantitative elemental analysis of the area pointed in the live SEM image. The system allows advanced microscope control in three levels of user expertise. Control by the keyboard, the mouse and the trackball or optionally by the Control panel is available via the VegaTC control software using the Windows™ platform
