Abstract

A probe head (10) suitable for Raman spectroscopy comprises an optical pathway (110) along which it is intended that light is emitted for illuminating a sample and light returns from the sample. The probe head further comprises an internal reference target selector (25) which allows to selectively bring a reference target (253) into said optical pathway, in which case the returning light, and thus the measurement signal, originate form the reference target, and to selectively provide free passage for the light to and from the sample, in which case the returning light, and thus the measurement signal, originate form the sample. The reference target has a known Raman spectrum. Measurement values from the reference target thus enable calibration of the Raman spectroscopy measurements. The internal reference target selector enables calibration without removing the probe head from a measurement setup.
