1. A spectrometer device configured for determining at least one spectral or spectroscopic information of at least one object,
wherein the spectrometer device is configured for determining intensities of constituent wavelength signals of at least one light beam propagating from the at least one object to the spectrometer device, wherein the spectrometer device comprises at least one distance detector,
wherein the at least one distance detector is configured for determining at least one distance information about a distance between the at least one object and the spectrometer device, wherein the spectrometer device comprises at least one pixelated imaging detector configured for determining at least one image of the at least one object,
wherein the spectrometer device comprises at least one evaluation device, wherein the at least one evaluation device is configured for determining at least one material information of the at least one object by evaluating at least one image of the at least one object determined by the at least one pixelated imaging detector,
wherein the at least one evaluation device is configured for determining the material information by applying at least one material dependent image filter Φ to the image of the at least one object determined by the at least one pixelated imaging detector, wherein the at least one material dependent image filter is an image filter having a material dependent output,
wherein the at least one material dependent image filter comprises a luminance filter; wherein the luminance filter returns a luminance measure of a spot as material feature, wherein the material feature Φm is determined by

OG Complex Work Unit Math
where f is a spot image, x denote the pixels of the imaging detector, n is a surface normal of the material, z is the distance, wherein a position of a light source is known as a parameter of the spectrometer device and dray is a difference vector between spot and light source positions,
wherein the at least one evaluation device is configured for performing at least one spectroscopic analysis of the determined intensities of constituent wavelength signals considering the determined distance information and the material information,
wherein the at least one evaluation device is configured for using the material information for pre-classifying the at least one object before performing a spectroscopic measurement and/or an evaluation of a determined spectrum.
