Claim 0:
1. A spectrometer apparatus comprising:
at least one light source configured to irradiate a sample with light;
an optical detector configured to detect the light scattered by the sample;
at least one optical filter device arranged in front of and/or behind the sample,
a contact sensor configured to determine a contact between the sample and the spectrometer apparatus and to output a corresponding output signal;
a control device configured to control the light source and the optical detector in response to the output signal;
wherein the control device is configured to activate the optical detector to detect the light scattered by the sample only when the output signal indicates the contact between the sample and the spectrometer apparatus is present and to deactivate the optical detector when the output signal indicates that contact between the spectrometer apparatus and the sample is absent such that the spectrometer apparatus takes measurements of the light scattered only when the output signal indicates the contact is present, and
wherein the control device is further configured to output an indication signal to a user when the output signal indicates that contact between the spectrometer apparatus and the sample is absent.
