Dear Dr. Bondarchuk,

We have been users of a Tescan equipment (a Vega II LSU, with a wide chamber, EDS detector and BSE, SE and STEM detectors) for more than 10 years at the Department of Chemical and Biological Sciences of Universidad de las Americas Puebla (UDLAP), and the instrument is still in a inmaculate condition thanks to the fine support from the representatives of Tescan in Mexico (Micra Nanotecnología). Aside of some minor problems (a substitution of the computer, and the very recent reparation of a high voltage module, which may have arisen from the recent movement of the instrument from one lab to another), we are very happy with this fine instrument which is very capable of giving very nice images for a good instrumentation cost (and technical services has been always good and responsible). We use it in a routinary fashion to analyze samples of diverse nature (magnetic nanoparticles, metal oxide semiconductors, nanofibers, noble metal nanoparticles, etc).

Hope and this feedback may be useful for you. Let me know if you have any question.

Dr. Miguel A. Méndez-Rojas, many thanks for your answer and consultation.

Dear Dr. Bondarchuk,

I have gotten the VEGA3 from TESCAN three years ago and let me tell you that all is fine. I am very happy with this STEM. It has a friendly platform to use, the equipment is highly efficient. Concerning the maintenance (which is the most import issue in Mexico) I am very happy with the support given by Micra Nanotechnology. Since the last three years we haven´t have any problems, more than replacing the filament, which usually shoud be changed after 200h of use. However, the last filament we repleaced had more than 400h of use. Please allow me to say that I strongly support and recommend this Vega3 STEM from TESCAN. These new types of microscopes are becoming more and more popular in many research labs. Besides this excellent performance, I would like to conclude my comment saying that in terms of price and quality, this STEM Vega3 from TESCAN is the most incredible SEM I have found for making high quality research and for teaching and habilitating students at all university levels. Please do not hesitate to contact me if you might have any additional questions. Sincerely yours,  Prof. Dr. Abel MORENO ([email protected])

Dear Prof. Dr. Abel MORENO, thanks a lot for your consultation. 

In October 2014 we began using the Tescan VEGA3 XMU Variable Pressure Scanning Electron Microscope at Texas A&M University and have had no significant problems. It is equipped with a SE detector for high vacuum, a SE detector for low vacuum, a backscatter detector and an Oxford EDS detector. A hot/cold stage is also supplied which can allow phase differences in materials to be observed in real time. The low vacuum option allows live specimens such as a C. elegans nematode to remain un-dessicated for live observation under the electron beam. The operation of the software is very intuitive which is a great help when training students unfamiliar with SEM. I tell my students that this is the easiest SEM to operate that I have ever used, and I started using SEMs in the mid-1980s. An absolutely fantastic instrument. Images acquired from this instrument have been published in Heritage Science (2016, vol. 4, pp. 1-7). Please contact me if you have questions concerning the use of this fine SEM.

Dear  Dr. Michael Pendleton, many thanks. Your comments are very useful for me.  

I purchased a Tescan VEGA3 for my company in the manufacturing sector. We loved the versatility of being able to image conductive and non-conductive materials. The non-conductive material imaging was surprisingly solid even with the physical limitations of that method. One of my favorite parts about the TESCAN was how easy it was to learn the system. The interface is extremely user friendly. It is almost too user friendly sometimes, which one would think could potentially lead to inexperienced users to get too cavalier with the equipment. TESCAN thought of this and has impact detectors that cause the unit to shut down if impact with the chamber walls or detectors. I never wanted to test the detectors, but we did test the chamber wall and it worked as expected. I would definitely be excited if I was touring a potential employer and they had a TESCAN in their lab.

Cheers

We are very happy with our VEGA 3, LM. Our demand for the work on the SEM is facilitated by the ease of use. Our Vega 3 is equipped with an SE, BSE and VPSE.

We have a Lab6 source that will provide us with constant service, for over 14,000 hours!!

When we vetted the SEM available, we found that for value of this instrument is high and not equaled. We strongly recommend this instrument!!

I have been in the field of electron microscopy in Mexico for over 35 years.

I am currently in charge of the area of electron microscopy at the institute of biotechnology at UNAM. In all this years I have worked with different brands of electron microscopes in Mexico. I have found that TESCAN microscopes has a high quality at very reasonable price. Beside the price an important point is the service and TESCAN in Mexico has provide an excellent service. I hope this information could be useful for you.

In 2013, our Physics department at Pará Federal University, Brazil has acquired a Tescan VEGA3. We enjoyed so much how easy is to learn the system and the versatility to get image for conductive and non-conductive materials. In line with the price and with excellent support service, Tescan VEGA3 has a excellent quality .

All the best

Thanks all for the inspiring details on TESCAN VEGA3 SEM. Does anyone have a price guide or who do I contact for quotation? Do they also have a good transmission electron microscope?

yes this is good thinks

who know about price of vega 3 lmu with tungestan filament. thanks for sending some information about this.@

the price depends on country where you are. we paid about 150 000 USD

what is the accuracy of measurments with it
