MEASURING APPARATUSES AND DEVICES FOR SPECTROSCOPICALLY EXAMINING SAMPLES

摘要

The invention relates to a measuring apparatus, which comprises a cavity (34) extending in a longitudinal direction (36), a first opening (35), which is to face a sample, a plurality of second openings (31) for detecting light coming from the sample, and at least one third opening (33) for coupling light into the cavity. Such a measuring apparatus is suitable in particular for spectroscopically examining planar samples.
