TESCAN is proud to introduce the new MIRA family of high performance microscopes equipped with a Schottky Field Emission electron gun.

At present we offer two models of MIRA according to the type of vacuum system:

The most important features:

• High brightness Schottky emitter for high-resolution / high-current / low-noise imaging.
• Unique three-lens Wide Field Optics™ design offering the variety of working and displaying modes embodying the Tescan proprietary Intermediate Lens for the beam aperture optimisation.
• Real time In-Flight Beam Tracing™ for the performance and spot optimisation integrating the well established software Electron Optical Design.
• Fast imaging rate.
• High-throughput large–area automation, e.g. automated particle location and analyses.
• Extraordinary analytical potential – 11 chamber ports with optimised analytical geometry allowing simultaneous EDS, WDS and EBSD
• Fully automated microscope set-up including electron optics set-up and alignment.
• Sophisticated software for SEM control, image acquisition, archiving, processing and analysis.
• Network operations and built-in remote access/diagnostics, all come as the Tescan standard.

The most important features:

• High brightness Schottky emitter for high-resolution / high-current / low-noise imaging.
• Possibility of examination of non-conducting, water containing specimens in their natural state at low vacuum conditions in microscope chamber
• Quick and easy achievement of clean working vacuum by means of turbomolecular and rotary pumps, easy and fast switch from high vacuum to low vacuum working mode
• Unique three-lens Wide Field Optics™ design offering the variety of working and displaying modes embodying the Tescan proprietary Intermediate Lens for the beam aperture optimisation.
• Real time In-Flight Beam Tracing™ for the performance and spot optimisation integrating the well established software Electron Optical Design.
• Fast imaging rate.

• VEGA || SBH / VEGA || SBU
• VEGA || LSH / VEGA || LSU
• VEGA || LMH / VEGA || LMU
• VEGA || XMH / VEGA || XMU

The VEGA series is offering a comprehensive range of sophisticated features:

• Excellent electron-optical qualities
• Ingenious column design with no mechanical centering elements, allowing simple operation and easy maintenance
• Quick and easy achievement of a clean working vacuum by means of a fully automatic turbomolecular-pumped vacuum system on high vacuum and variable vacuum models
• Flicker-free imaging with super clarity and brilliance as a result of the high quality digital image acquisition and processing system
• Fully automated set-up of the microscope and many other automated procedures
• Sophisticated software for microscope control and image capture, as well as image archiving, processing and analysis
• Remote control of the microscope with the possibility of remote diagnostics, which can reduce service costs
• Unique SE detectors for low vacuum operation (LVSTD)

Two types of the vacuum system are offered:

VEGA II H (H igh Vacuum SEM) - conventional model operating at a high vacuum of approximately 5x10 -3   Pa.

VEGA II U ( variable pressure SEM) - which combines the advantages of the basic VEGA LSH with extended facility for low vacuum operation. In low vacuum mode, nonconductive specimens can be examined in their natural, uncoated state, using all working modes of the optical system at pressures up to 150 Pa and in Resolution mode at pressures up to 500 Pa (operation at chamber pressures up to 2000 Pa optionally available).

At present VEGA family includes 8 models of microscopes provided with various chambers according to the users´ requirements concerning chamber size, stage movements precision and/or operation comfort. Abundant control software included in standard scope of delivery is one of the valued assets of the Vega microscopes.

The microscope control software can be extended by other optional software modules according to the users´ requirements. Also, wide choice of supplementary accessories and detectors is one of many benefits of the VEGA microscopes.

The unique four-lens electron optical column allows the optical system to be used in various modes:

• Resolution mode provides the highest resolution for the chosen working conditions
• Depth mode provides an enhanced depth of focus
• Field mode allows an extra large field of view
• Wide field mode provides a macro view of the sample 
• Rocking-beam working mode for assessment of crystal orientation data of the specimen, acquiring of electron channeling pattern (ECP)

The optical system of the variable vacuum Tescan SEMs is designed to ensure the highest possible resolution, as well as quick and easy switching between the high and low vacuum operating modes.

Tescan SEMs can be delivered with different chambers and stages, as well as a comprehensive range of optional accessories. Tescan works closely with all the SEM accessory vendors to ensure compatibility and trouble-free integration.

Demands for the working conditions and for the minimum area necessary for the installation of the microscope are as usual.
