Abstract
A pyrometric detection device for use in an apparatus for producing three-dimensional work pieces comprises a pyrometric detecting unit () configured to receive thermal radiation emitted at different points of a detection plane in a detection direction and a calibration device () comprising a substrate () and a plurality of light guides () each having a first end () for coupling light into the light guide () and a second end () for emitting light from the light guide (), the second end () being fixed to the substrate (). The substrate () is adapted to be removably arranged relative to the pyrometric detecting unit () in such a manner that the second ends () of the plurality of light guides () are arranged in the detection plane and emit light in the detection direction, in a calibration state of the pyrometric detection device.
