Innovative Variable Beam Splitters
Adjustable Beam Splitters from LASER COMPONENTS
Press Release
11.10.11
High power beam splitters are used to split a laser beam into two partial beams.
Conventional production of such a dielectric layer has a tolerance of ± 3% or higher.
With a special IBS coating, offered by LASER COMPONENTS, the tolerance can be reduced to just ± 1%.
In very challenging applications a laser user will want to avoid tolerances of
even ± 1%. In addition, there are applications in which one ends up with different
losses in each beam path after adjustment.
For these applications, LASER COMPONENTS has designed a variable beam splitter
that has a position-dependent reflection profile. By moving the beam splitter
one can obtain a reflection value between ± 5% depending on the position.
The values can be continuously adjusted. The coating is produced using an IAD process;
therefore, it does not exhibit a noteworthy drift. Due to the active adjustment,
the laser beam cannot only be very precisely split, but it can be split without any absorption losses.
