Abstract

For far infrared measurements, pre-detector filtering is necessary for special applications. Hexagonal close-packed arrays of precision drilled microholes can be used as high pass filters for the far infrared1. They are fabricated, for instance, using the mechanical microfabrication methods developed at the Karlsruhe Nuclear Research Center, i.e., microdrilling with hard metal drills of variable diameter down to 50 pm 2.
