30 years of Topas

For three decades an integral part of global industry and primary research

Thirty years can be short or long. In the niche industry of aerosol and particle measurement, they have been a remarkable time for us.

Since 1991, technology-oriented particle analysis and sensor systems have been developed, designed, and manufactured under the name Topas. In the past thirty years, we have established ourselves as the specialists for generating, conditioning, and analysing test and reference aerosols. In the process, we have grown to be a mid-sized company, contributing to global industry and research from Saxony in Germany. For decades, our more than 60 product series and 20 available test systems have established the name Topas as the standard for the classification and testing of filters and filter media.

Founded by three ambitious tinkerers and budding entrepreneurs as a spin-off of the Technische Universität of Dresden, we have worked to earn our place as a sought-after partner in the scientific field. We were gratified to see our work recognized as, since the beginning of the COVID-19 pandemic, we have had the opportunity to actively contribute our expertise in scientific and technical issues to the efforts to contain the infectious disease.

With the anniversary year beginning on the first of February 2022, we have many reasons to celebrate: more than 45 patent and utility model applications and 7 registered trademarks, around 12,000 precision instruments and 800 sophisticated testing systems produced, over 1,000 entries in scientific publications and almost 100 enthusiastic employees. Over the next 12 months, discover many exciting stories and previously unknown anecdotes from the 30-year company history here.

Pictures say more than a thousand words

A real good reason to celebrate

On 10 September, we let it rip. The Topas staff and their families celebrated 30 years of company history with long-time companions. With these pictures we remember a wonderful event in the middle of our anniversary year.

Simply explained: What connects a gemstone with a modern technology company?

Again and again, we are asked what our company has to do with the precious stones, the topazes, which are popular all over the world. This year is the year of topaz for mineralogists. And therefore, a nice occasion for us in our anniversary year to draw a (not entirely serious) comparison.


The name topaz is presumably derived from a Greek spelling of the present-day Egyptian St. John's Island. There were probably precious stones there, but they were only called topazes by mistake. Our name, in contrast to that of the crystal, clearly comes from the mind and pen of our three company founders: Topas stands for technology-oriented particle, analysis and sensor technology, with the five initial letters forming the company name. Among other things, the beginning of the name is reminiscent of a support programme of the Federal Republic of Germany in the 1990s for technology-oriented companies, which we were able to take advantage of. Topaz is known and loved above all for its wide range of colours, from yellow, yellow-orange and yellow-brown to reddish-brown, pink and rose-red to light blue and, rarely, light green. Obviously, we also have a faible for colour – which makes the yellow technology company equally colourful and clearly identifiable in the amount of aerosol and particle device technology.


Like the magnificent gemstone, we are represented on all continents by a worldwide sales network. Our export quota is more than 75% at the moment. Interested parties can contact our partners in over 40 countries worldwide. In Germany, topazes are mainly found in Saxony - we too are a Saxon company and are located in the state capital Dresden since the company was founded in 1992. The Saxon Elector Augustus the Strong was particularly fond of his jewellery made of Vogtland topazes from the world-famous Schneckenstein topaz rock, which can be admired today in the Green Vault in Dresden. Topaz aerosol and particle technologies are also highly valued – in a variety of industries, by well-known filter or automobile manufacturers or in (basic) research at universities and numerous scientific institutes. Analogous to the great strength of the crystal topaz with a mineral Mohs hardness (MoH) of 8 after corundum and diamond, our customers can count on consistency and stability in the economic relationship as well as on durable and high-quality technologies and equipment since the beginning.





As "Saxon diamonds", the topazes from Schneckenstein also sold very well to the English King George III. Of course, we do not compare ourselves with the indestructibility of a diamond. But we hope that our devices and equipment represent a certain object of value for their owners and support their production, research and development as a high-quality and innovative product in the best possible way. If you would like to know more about topaz, you have the opportunity to do so until 24 June 2022 in the current cabinet exhibition at the Gera Natural History Museum.


By the way: We are particularly excited about the healing powers attributed to topaz. As a stone of self-realisation, it is said to stand for the development of one's own abilities. A point that is particularly close to the heart of one of our company founders, Dipl.-Ing. Christian Peters: Topas employees (internally also called “Topase”) have many creative possibilities and should be allowed to contribute their strengths in order to further advance Topas and discover exciting fields of work for themselves. Read more in the founder interviews in the anniversary section below.

We have many reasons to celebrate

We can hardly believe it ourselves what has happened in three decades. Lots of exciting and curious facts from 30 years of Topas have been compiled by our team. Take a look for yourself.


Progress is never a coincidence.
