Patents 


Since its foundation in 1913, Schneider-Kreuznach has acquired many German and international patents in the field of precision mechanics/optics based on its core competencies. This has resulted in many brands such as Xenon, Symmar, Xenoplan, Variogon, Cinelux, etc.

The patents include optical systems for photography and cinema projection - lenses for recording, magnification, projection, television - as well as those for industrial applications and a large number of servo-hydraulic and servo-pneumatic innovations. They can all be found in a wide range of applications in a variety of industries. The following table gives a brief overview of EP, US and DE patents.
