Abstract: A skin measuring device for spectroscopic measurement of the skin of a body part is provided. The skin measuring device has a press-on frame with a window and a flat face. The skin measuring device has an ATR infrared spectrometer which includes an ATR crystal that is secured to the press-on frame and that has a sample stage which is arranged in the window and faces in the same direction as the flat face of the press-on frame. An encircling means surrounds the body part and thereby supports the skin measuring device on the body part. The surface of the flat face of the press-on frame is pressed against the skin of the body pan by the encircling means in a comfortably wearable manner when the skin measuring device is worn such that the sample stage is in contact with the skin for spectroscopic measurement by the ATR spectrometer.

Abstract: The invention relates to an ATR spectrometer for analysing the chemical composition of a sample, wherein the ATR spectrometer (1) comprises an ATR crystal (2), at least one infrared light source (5) being arranged on the entry surface (3), a line array (6) of infrared light detectors, at least one single infrared light detector (7), wherein the at least one infrared light source (5) is adapted to emit infrared light that enters the ATR crystal and is guided to the infrared light detectors under total internal reflection and under interaction with the sample being arranged immediately adjacent to the ATR crystal, a wavelength dispersive element (8) being arranged in the path of the infrared light so—that the line array is adapted to measure a spectrum of the infrared light, and a wavelength filter (9) being arranged in the path of the infrared light to the single infrared light detector, wherein at least one of the infrared light detectors is chosen to be a chosen infrared light detector for a signal correction, and the ATR spectrometer is adapted to use the electrical signal of the chosen infrared light detectors to correct the electrical signals of all the other infrared light detectors.
