Others
While all the coatings shown before are specifically designed for dispersion control there usually is the need for more kinds of optical filters.
When working with femtosecond laser pulses it is important to know at least their dispersion. On request, we are able to provide dispersion information even for our coatings which are not optimized in this regard.
The example shows a thin film polarizer (TFP) at 1030 nm with GDD tolerances for the reflected and transmitted wavelength.
Examples
If not mentioned otherwise, all values and diagrams are given
... for the standard substrate material used in the described wavelength area (mostly Fused Silica or CaF2).
... without consideration of the rear surface.
... with EBE coating technique for a good cost-performance ratio.
Customized coatings are available for all types.

Every coating type can be optimized
for every
• substrate material
• wavelength
• reflection/transmis-
sion value
• angle of incidence
• polarization
• GDD value
• ...
Alternatively we can create
a totally new design for you.
