1. An assembly comprising
a source of electromagnetic radiation;
a detector assembly comprising a detector for electromagnetic radiation, wherein the detector assembly comprises a detector assembly receiving end positioned to receive at least a part of the electromagnetic radiation from the source,
wherein at least part of the electromagnetic radiation received at the detector assembly receiving end is received by the detector;
a source optical element configured to transmit electromagnetic radiation received at a receiving end of the source optical element to an emitting end of the source optical element,
wherein the receiving end is configured to receive electromagnetic radiation of the source,
wherein the emitting end is configured to emit the transmitted electromagnetic radiation, and
wherein a first direction is defined by a light path between the emitting end and the detector assembly receiving end;
a tube assembly comprising a portion of a tube, wherein the tube assembly is positioned between the emitting end and the detector assembly receiving end in the first direction,
wherein the tube assembly is movable to change its position, and wherein an amount of electromagnetic radiation received by the detector depends on the position of the tube assembly,
wherein the source optical element suppresses the transmission at least for 90% of wavelengths in the range of 2.2 μm to 10 μm by at least a factor 10;
wherein the source optical element is a waveguide.
