Embodiment Construction

[0030] In the figures, identical reference numerals indicate identical or functionally identical elements.

[0031] figure 1 ) is a schematic diagram of a spectrometer device with a sample according to a first embodiment of the present invention.

[0032] exist figure 1 ), the spectrometer device 10 includes: two light sources 11; a detection device 12, which includes an optical filtering device 13 and a photodetector 14; contact sensing devices 15, 16, which include ambient light The sensor 15 and the inertial sensor 16 ; and the control device 17 , which is connected to the contact sensing device 15 , 16 , the detection device 12 and the light source 11 . Here, the sample 18 is in contact 19 with the spectrometer device 10, which means that the sample 18 is physically in contact with the spectrometer device 10, or the sample is placed very close to the spectrometer device.

[0033] The two light sources 11 shown here are angled such that the illumination field overlaps eg...

Abstract

The invention relates to a spectrometer apparatus (10) having at least one light source (11) for irradiating a sample (18) with light, an optical detection device (12) for detecting light scattered by the sample (18), at least one optical filter device (13), which is arranged in front of and / or behind the sample (18), a contact sensor device (15, 16) for determining a contact (19) between the sample and the spectrometer apparatus (10) and for outputting a corresponding output signal, a control device (17) for controlling the light source (11) and the detection device (12) in response to the output signal, wherein the control device (17) is designed such that the control device modifies at least one operating parameter of the light source (11) and the detection device (12), when the output signal indicates the contact (19) between the sample and the spectrometer apparatus (10). The invention further relates to a method for operating a spectrometer apparatus (10).

Description

technical field [0001] The invention relates to a spectrometer device and a corresponding method for operating a spectrometer device. Background technique [0002] Spectrometers are essential in many fields of science for the analysis of any type of sample. In recent years there has been a trend towards miniaturization of spectrometers, since these can thus be used more flexibly. A spectrometer usually consists of a light source, a spectral filter, and a detector. Here, the filter is placed between the light source and the sample or between the sample and the detector. Thus, US patent publication US 7061619 B2 describes a miniaturized spectrometer. [0003] With the proliferation of cell phones and smartphones, the idea of ​​integrating a spectrometer into a handheld device was born. This means that the spectrometer can also be used on the road and the detected spectra can be freely and openly stored for each user, for example in the cloud. In this way, the spectra may ...
