Only in a few niche areas CRTs are still the display of choice or are needed for recurring replacements. Avionic platforms like aircrafts and helicopter with long lifetimes of the systems require constant maintenance and a secured availability of spare parts.

The origin of Dr. Gassler Electron Devices traces back to the old German company Telefunken, which built the first CRTs for integration into an aircraft more than 70 years ago. The successors of Telefunken: AEG, Thomson, Thales and Samtel added many different designs to the huge archive of specifications and manufacturing files of the today company Dr. Gassler Electron Devices.

At Dr.Gassler Electron Devices we believe in the unique technical possibilities of electron beams and we are using our core competences to develop and manufacture electron systems for various applications. Electron guns designed originally for CRTs are adapted to the specific needs of applications in the scientific world as well for medical applications. These new applications, built on the same basic technology as CRTs, guarantee the support of CRTs also in the future. Even when total requirements for CRTs may be further reduced, our new other applications allow us to continue the supply of professional CRTs also in the coming years.
