FIELD: physics.
SUBSTANCE: device has a laser radiation source, a solid-state sample with a flat surface which guides surface electromagnetic waves (SEW), an element for converting volume radiation into surface electromagnetic waves and a photodetector placed at the surface boundary in the radiation incidence plane and connected to a measuring device. The sample is made in two parts with matched flat surfaces lying in one plane. The conversion element is fixed relative the flat surface of the first part on the path of the radiation. The photodetector can move along the line of intersection of the radiation incidence plane and the flat surface of the sample, and the second part of the sample is detachable.
EFFECT: cutting on time and more accurate measurement.
