where passion       meets know-how

Since its start up in 1946 the company has been located in Leverkusen, close to Cologne - western part of Germany. This area is noted for its excellent infrastructure and highly skilled employees. Today there is a CNC component supply facility separate from the parent firm.

the art    of x-ray

We produce every individual component ourselves. That way we keep a continuous control of the results. Additional to this it allows us to quickly transform new tube models or variants of existing models. Our long history of experience in this area, makes it possible for us to implement complex components for single or series tubes.

less is more To construct high-performance and reliable X-ray tubes we strive to keep the material used to a minimum. With our unique technology a complete vacuum can be created, without the need to adopt the usual “Getter“ (chemical reactive material): the result is an unusually long service life. Additional to the numerous quality tests during production, we carry out repeated functional tests at high-voltage for each individual X-ray tube. In spite of all the experience, the manufacture of an X-ray tube remains a complex and high-risk process. That is why the substantial effort involved for all the fail-safe testing is an investment well made.

Well reputed as a reliable and loyal source we are supplying to worldwide market leaders with high volume applications like: • Non Destructive Testing (weld or aircraft inspection and many others) • Security applications (baggage inspection, letter bomb detection, etc.) • Gauging (metal thickness gauging in the steel industry) • Medical applications (Radiography, CT, densitometry) • Food industry (contaminants  detection)

the family business

1930s. Dr. Franz Lohmann in his laboratory. Lohmann X-Ray GmbH has been founded in postwar (West-) Germany as a private enterprise by Dr. Franz Lohmann in 1946 to produce X-Ray tubes for industrial applications.

Franz Lohmann Since the 1930s Dr. Franz Lohmann has been investigating vacuum technology. On the 1st January 1946, out of the ruins of the Second World War, he built his small X-ray tube factory and in so doing literally laid the foundations for the process that isstill being used today. In 1956 the plant was moved within Leverkusen to its current location. In the first phase of production the company specialized in tubes for medical treatment, rectifier tubes and tubes for NDT (non- destructive testing) that were at first small commissions for customers in Germany and around Europe.

Hermann Lohmann In 1968 the company was taken over by son, Franz Lohmann passing it on to the second generation. Under his command the NDT side of the business was upgraded, an own line of X-ray equipment was developed and distribution was expanded into the USA and many other countries. In the early 1980s amongst other things the company became leader in the market for baggage inspection machines at airports, as well for specialist medical machines. The quantity of X-ray tubes produced increased steadily resulting in the building of the company’s first extended annex.

Lothar Lohmann 1990   saw   Lothar   Lohmann   as   third   generation   family   member   commence   his   work   for   the   company,   which   he eventually   took   over   from   his   father   in   2001.   Optimized   processes   allowed   the   production   number   of   tubes   to   be increased   with   some   additional   characteristic   improvements   on   them.   Additionally   the   market   was   opened   into Asia   and   new   applications   were   introduced,   e.g.   in   the   medicine   sector   and   for   food   inspection.   At   present   a   newly built company annex houses the glass technique department. The component themselves are manufactured at a  different location.
