Thomas Carlsen

Thomas has been a translator since 1993.

At first, as a graduate sinologist having majored in Chinese and German, he worked exclusively within the software industry, specialising in graphics software, printing and telecommunications.

With this background, he was one of the first translators in Germany who succeeded in taking advantage of the speed of the “information superhighway” from the earliest days of the Internet, at a time when many people still wondered whether exchanging their typewriters for a PC was really such a good idea.

Thomas, on the other hand, saw his business grow exponentially, which enabled him continually to add new services to his portfolio.

Based in Hamburg and working with a worldwide team of more than 50 highly qualified freelancers, Thomas Carlsen Fachübersetzungen, now a fully fledged translation agency, looks back on a long list of satisfied international clients. With its numerous contacts and partners around the globe, the agency has, over the last two decades, become the epitome of accuracy, elegance and clarity in translation.
Thomas Carlsen Fachübersetzungen is an experienced partner for all your translation, document preparation and technical manual drafting needs!

 lTranslations have to work. 


A translation project in 10 languages?

Pedal to the metal

You want to pay less?  We also offer volume discounts for large amounts of text. If you so wish, we can also take into account repetition and Translation Memory matches when developing your quote. Just ask.

We can bill according to both the customary traditional Central European standard line basis on the target text or on the international per word of source text standard.

No problem!  In 20 years we have translated many millions of words into all major world languages and also into some of the less common ones.


Multilingual translation projects are our daily business. Due to the nature of their operations, some of our customers require only such multilingual services.
Experience tells – especially after so many years. Try us out!

Good timing is everything! If you need big amounts of text translated, it is advisable to let us known in advance, and also to allow for adequate time for the translation in order to avoid scheduling problems at the end of the supply chain. And if it should simply be an urgent matter, rest assured – we have already, hundreds of times, proven that we can also work wonders.
Just ask us! We can help you plan your schedule with guidelines about the time required to produce a quality translation.

File formats

Translation is craftmanship!


We translate all common Office formats, such as Word, Excel and Powerpoint, as well as layout files from InDesign (several versions), Illustrator or Acrobat.

To translate PDF files we ideally need the original template - e.g. in Word, PPT, InDesign or Illustrator format.

The human brain translates in real time, with a high level of accuracy and contextual understanding. And yet, in these times, when knowledge expands at an astronomical rate on a daily basis, technical aids are essential. Translators work with Translation Memory systems that record their translations in a database and then compare future versions of the same document with the existing records. These tools can help save time and accelerate the translation process while ensuring consistency.

We always keep a watchful eye on the latest technical developments and apply them whenever we deem them to be useful for our work.

We are subject to strict laws concerning the confidentiality of your data. And we comply with them. When translating certain types of documents, e.g. stock exchange relevant texts, additional specifications may become necessary, which we will of course comply with.

Our project server is encrypted using 2048-bit technology. Clients can be granted access to it upon request in order to transfer confidential data directly and use our internal communication system.

And this is what you can expect from us, of course in addition to top quality translations:

- Mother tongue translators with qualified professional degrees, diplomas or certificates, specialising in the

   pertinent subject matter

- As a standard, we apply dual control – i.e. the editorial principle according to which texts are proofread by

   a “second set of eyes” – and at least treble control for sensitive texts intended for publication

- Punctual delivery

- Professional project management

- Translation Memory systems to ensure consistency and reasonable prices

- Terminology management

- Proactive and reliable communication

We support the Mars One Project


In 2012 we became aware of the Mars One project. At that time, Mars One needed specific translation assistance in order to be able to get the project off the ground. We enthusiastically translated content for Mars One into several languages, as we are firmly convinced that this project has trailblazing potential. It is our hope that it will be as useful to humankind as the first lunar landing in 1969.


You will find a listing of the translators who participated in this project here.
