Claim:
1. A system for infrared spectroscopy of a sample using attenuated total reflection, comprising: a light source producing a light beam; a reflection matrix having a multiplicity of reflection elements arranged on a matrix surface, the reflection elements being configured to guide the light beam by total internal reflection, a first subregion of each of the multiplicity of reflection elements having an application surface with a convex exterior shape, the application surface facing toward the sample to be spectroscopically analyzed, a second subregion of each of the multiplicity of reflection elements defining a transverse perimeter channeling the light beam into the first subregion of the respective reflection element and out of the first subregion and thereby out of the respective reflection element, the reflection elements being arranged in a matrix and disposed regularly in two mutually perpendicular directions of the matrix surface; a multiple reflection crystal configured to guide the light beam by total internal reflection multiple times to one of the reflection elements; beam shaping components directing the light beam at least one of to and from the multiple reflection crystal; and a detector detecting the light beam after reflection by the reflection matrix.
