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.




Grad. Edge filter GEF


Combination of gradient long wave with gradient short wave pass filter.

Shifting the plates independently, the bandwidth of the resulting band pass
filter can be varied from 30 nm to 150 nm.
By shifting the plates simultaneously in the same direction, transmission can be tuned throughout the visible.


GNF 750 nm
Gradient negative filter, variable in the range 700-800 nm.

Width of the reflection band 50 nm, reflectivity > 99.7% in the center, average transmission > 90 % outside, if coated with BBAR on the back side.

Damage threshold
as high power mirrors
