History - Components B History - C-Stand History - Application

Our company was founded 1943 by Oskar Uhl, the father of Walter Uhl. During this period, objectives, eyepieces and dovetail z-drives for microscopes were produced. When Walter Uhl has taken over the company from his father, he has created and intruduced a component system containing single tube elements like clamping boxes, beam splitter cubes, filter inserts and raster bore plates.

Most of our products like positioning systems, measurement microscopes, custom systems and even the software are based on this basic idea of modular components.

In 2000 we have taken over the hand driven measuring microscope VMM series from Leica. Now we produce and distribute these instruments under our brand. We are the last german manufacturer who has a complete measurement microscope product range.

The low-load microhardness tester VMHT was also taken over from Leica in the year 2005. Now, further development is done continously by us.

Design and product development - 3D-CAD workstation Software development and technical documentation
Our own design and software development department gives us the ability to design, produce, assemble and distribute a product by ourselves completely.

Manufacturing - CNC turning Manufacturing - CNC milling Manufacturing - high precision finishing
With a high manufacturing depth, we can solve customer requirements flexible and quickly. A constanly high quality is guaranteed by that too.

Assembly - laser interferometer measurement Assembly - VMM measuring microscopes
The assembly area has a climate controlled measuring room in which e.g. the positioning accuracy of the measuring microscope stages is certificated according to VDI/VDE 2617.

Presentation room - demonstration units Presentation room - demonstration unit Presentation room - meeting and training
In our presentation room, we can demonstrate most of our instruments, together with the customer we can do test measurements. It is also used as in-house product training facility for one or more days (date arrangement recommended).

Qualification - in-house education movie about qualification in the craftsmanship (in german)
Mr. Uhl has established a training workshop, equipped with machinery and classroom, in the old company building. Young trainees are qualified as "Feinwerkmechaniker" - industry mechanic - by a master craftsman.
