Optimized thin film coatingswith IBS
This article (in german) by Dr. Wolfgang Ebert and Tobias Groß (published in "Laser+Photonik", Iss. 1, March 2010, p. 30-34) discusses and compares the different coating methods found at LASEROPTIK with focus on IBS process and its special possibilities.

LASEROPTIK started an "open door" day on September 3.,2009. A lot of visitors came in to congratulate, celebrate and inform themselves about the capabilities of our production. A photo gallery of LO OPEN can be seen here or at menu item "About us > 25th anniversary".A short article (in german) describes the day and the celebrations at the "Laserhof" in Garbsen.

Magnetron Sputtering
was established at LASEROPTIK after a two year joint r&d effort with the engineering experts from DSI Inc., USA. As a result LASEROPTIK were the first using a unique sputtering technology in October 2001, that is best described by DSI's Microdyne principle*:
"In a magnetron sputter system, there are cathode assemblies containing magnets. The face of these cathodes has a plate of coating material called a target. After the coating chamber is evacuated, it is backfilled with a working gas, typically argon. A voltage is applied to the cathode assembly. The electrons are contained in front of the cathode by the magnetic field. As electrons hit the argon atoms, the electrons are knocked off the argon atoms, causing them to become positively charged. A plasma of ionized argon forms in front of the target. The positively charged argon ions are accelerated toward the negatively charged target, where they strike the face of the target-ejecting metal atoms.
During this process, a reactive gas, typically oxygen or nitrogen, is introduced. To ionize the gas, Deposition Sciences employs its MicroDyn System using a microwave source. The gas combines with the metal atoms from the target to form the desired metal oxide or nitride. Typically, the material sources, or targets, are around the periphery of the chamber, and the substrates are held on the surface of the drum in the center. The drum rotates so all parts are coated."
Special areas of application are
- oxide, nitride or hydride coatings from 190nm to 20µm
- hard, mechanically resistant layers
- environmentally stable coatings (especially regarding temperature, moisture)
- low temperature coatings on plastic or other non-glasslike materials (e.g. fiber ends)
- high damage thresholds
- extremely steep slopes
- big substrate sizes.
