In optics and sensor technology, things have to be done very precisely. Ideal conditions for the use of etched parts by Herz which are renowned for their high precision. Use black oxidized etched parts for light absorption, for example. Benefit from burr-free edges which deliver sharp images in projection. And you can rely on absolutely planar parts, guaranteed by the Herz etching process.
Delicate webs are incredibly important for both optical and sensory components, for example sputtering masks. After all, in the case of very narrow webs, only the best edge finish is a guarantee for perfect sputtering results.
Where light scanning reaches its limits due to a rough and dirty environment, magnetic scanning can be used. In these highly sensitive systems, partially etched web/channel structures can help to produce reliable signals in difficult environments.
