   Tescan biography:

TESLA used to be the leading supplier of electron-optical devices and electronic measuring instruments in Eastern Europe and so TESCAN follows up with this activities taking advantage of the long-year-experience of the best specialists. The close co-operation with universities and scientific institutes is another strength of the company.

TESCAN was awarded (recognized) as an innovative company of the year in the Czech Republic of the year 1994. TESCAN succeeded in several research projects granted by European Community or Czech government (Copernicus, Technos, etc.).

In order to make use of the advantages of own mechanical workshop, TESCAN launched the machine tool manufacturing for German clients. This made possible to equip the workshop with new, high precision machinery. The position of the company strengthened in 1996 when TESCAN purchased own real property.

Since 1993, Nouavar Shad Co., has provided high quality, dependable scanning electron microscopy products and services. Representing one of the world’s premier manufacturers "Tescan a.s.", Tescan offers an exceptional range of scanning electron microscopes - from compact, economical models to ultra-high performance research grade instruments. And with a nationwide team of experienced service engineers, you’re assured of fast, expert support for the life of your SEM.

MIRA Schottky Field Emission Scanning Electron Microscope 

TESCAN is proud to announce the launch of the new Mira series of field emission scanning electron microscopes. The Mira FE SEM uses a high brightness Schottky-emitter for high-resolution / high-current / low-noise imaging, that also provides excellent stability for high-throughput large-area automation, like automated particle analyses. The Mira employees a unique Wide Field Optics™ design offering a variety of imaging modes that use the Tescan proprietary Intermediate Lens for beam aperture optimization. The Mira also uses real-time In-Flight Beam Tracing™ for performance and spot optimization. The Mira shares the control system used in Tescan’s Vega-II, tungsten-emitter SEM which includes: a Wide Field Optics™ column with Fisheye and depth mode imaging, fully automated set-up and alignment of the electron gun and column, and an integrated suite of imaging software designed for multiple user environments that includes functions for acquisition, archiving, measurement, analysis and reporting of images and data. Network and remote SEM operation are standard functions on every Tescan SEM. 

 

Each Mira and Vega 3 SEM includes a Back-channel diagnostics system that monitors several hundred points throughout the microscope allowing Tescan engineers to keep each instrument running at peak performance.
