Claim 8:
9. A method for operating a spectrometer apparatus comprising the following steps:
positioning the spectrometer apparatus relative to a sample;
checking for existence of a contact between the spectrometer apparatus and the sample with a contact sensor; and
activating an optical detector of the spectrometer apparatus to detect light from a light source of the spectrometer apparatus scattered by the sample only when the contact between the spectrometer apparatus and the sample is present and deactivating 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
when contact between the spectrometer apparatus and the sample is absent, outputting an indication signal to a user.
