Fiber Coating all around

We coat your fibers all ‘round!

As pioneers in atomic layer deposition (ALD) for optical coatings we can coat on a variety of complex geometries and substrates.

For example, with a conformal AR coating all around a fiber lens surface. A residual reflection of <0.25 % and a coating distribution of <1% on overall thickness (TEM results) help to reduce losses when collimating light from diodes within fiber array packages (FAP). Even fiber lens diameters below 100 µm are available, can be coated for the desired wavelength and precisely cut to the specified length.
