TESCAN VEGA

Analytical SEM for materials science and life science applications in research and industry

World’s most versatile and powerful tungsten SEM for both high- and low-vacuum operations

Key Features
- Fully integrated imaging and EDS - Essence EDS combines SEM imaging and elemental composition in a single window
- Optimal imaging and analytical conditions - Optimised using TESCAN’s in-flight beam tracing
- Simplified navigation - Using TESCAN’s Wide Field Optics locate areas of interest from as low as 2x magnification
- Deal with charging and beam sensitive samples with just one click - Using SingleVac mode
- Effortless and customisable user interface - Essence software simplifies operation and allows each user to customise their own workflow
- Expandable analytical capabilities - Designed for incorporation of extra detectors e.g. WDS, EBSD, CL etc.
- A highly sophisticated motorised 5-axis stage - Allows for automated procedures such as large area imaging, saving point of interest, etc.
- Fully automated column - No mechanical centring elements, enables fully automated column set-up and alignment

The TESCAN VEGA is a highly reliable and versatile SEM that offers high-performance at an attractive cost. With the addition of TESCAN’s Essence software it will allow even novice users to image like seasoned professionals.

Live View Window with Integrated EDS

TESCAN VEGA integrates SEM imaging and optional Essence™ EDS in one live view window to make analytical operation fast and easy. Essence™ EDS is as simple as a single mouse click optimising all set-up parameters through the software, initiating elemental analysis of the sample. Fully integrated Essence provides immediate access to the elemental spectrum at any point or region, presenting the data as an elemental map or point/line EDS spectra.

Optimised Imaging and Analytical Conditions

An innovative optics design guarantees immediate and seamless selection of either imaging or analytical conditions as required, without the need for mechanical re-alignment of any in-colum element. Using a unique additional Intermediate Lens™ powered by TESCAN’s In-Flight Beam Tracing™, you can continuously increase beam current to a value that optimises signal to noise ratio for imaging at the desired magnifications and accelerating voltages.

Furthermore, switching from low voltage imaging mode to high voltage analytical modes is achieved with a single mouse click.

Precise SEM Navigation

TESCAN’s unique Wide Field Optics™ mode provides you with a live SEM overview and a more intuitive navigation process with an unprecedented depth of field and a view o the sample’s actual topography. Continuously zoom in on your area of interest from 2x magnification using the live SEM view window.

Intuitive and Modular Essence User Interface

The 4th generation VEGA benefits from TESCAN’s Essence multi-user software interface which has been designed so that each user can streamline the user interface to their own specific requirements. This allows you to define workflows that match their level of experience and/or specific application need.

SingleVac Mode for Charging and Beam Sensitive Materials

Supplied as standard, SingleVac mode uses factory-preset pressure to optimise imaging conditions of charging samples without the need for conductive coatings.
