All values are given for standard coatings. Customized coatings available for all types.
Coating methods available:





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.

1064 nm: T 25-75% min. variation on substrate
(IAD-coating). Find here more details about Gradient Output Coupler GOC.
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.
