From Night Vision Wiki
Harder Digital is a German manufacturer of image intensifier tubes.[1]
It is possible that Harder Digital uses cores produced by Katod in their image intensifiers.[2]
Harder Digital mostly sells to government agencies, and are rarely found on the civilian market.
As the only third generation image intensifier manufacturer in the EU, while being relatively small, their prices for their image intensifiers are much higher compared to other manufacturers around the globe.
