4 new IBS coating machines

Double IBS capacity in 2015
LASEROPTIK enlarges from four to eight industrial IBS systems e.g. for ultrafast optics, complex filter designs or in the UV. With a custom built giant machine, LASEROPTIK also offers coatings on substrates up to 2 metres in length, made by IBS.

IBS coatings up to 2 m





LASEROPTIK now designs and produces dispersion-matched pairs of broadband chirped mirrors for even better GDD compen-sation.

 

 

 



Magnetron Sputtering

was established at LASEROPTIK after a two year joint r&d effort with US engineering experts. As a result LASEROPTIK were the first using a unique sputtering technology in October 2001, that is best described like this*:

"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. 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.
