Abstract: An apparatus includes an integrated sensor module for detection of chemical substances. The sensor module includes a UV radiation source operable to emit UV radiation onto a sample. The sensor module also includes a sensor including dedicated channels disposed so as receive UV radiation reflected by the sample. Each of the channels is selectively sensitive to a different respective portion of the UV spectrum; collectively, the channels cover at least part of the UV spectrum sufficient for reconstruction of a spectral curve of the sample. An electronic control unit can be used to identify a composition of the sample based on signals from the channels.

Abstract: An integrated sensor module includes a UV radiation source operable to emit UV radiation onto a sample, and a sensor including spectrally sensitive UV channels disposed so as receive UV radiation from the sample. Each of the UV channels includes a respective sensing device and a respective UV interference filter disposed over a UV radiation sensitive portion of the respective sensing device. The respective UV interference filter for each particular one of the channels has transmission characteristics that are spectrally responsive to a spectral signature of a respective chemical substance.

Abstract: An optical sensor device comprises a first and a second optical sensor arrangement. In the first optical sensor arrangement at least one optical sensor structure measures the incidence angle of incoming light that is approximately on the main beam axis of a light source. The second optical sensor arrangement comprises at least one optical sensor structure with at least one optical sensor, at least two metal layers and opaque walls optically isolating the optical sensor. An evaluation circuit provides an output signal of the second optical sensor arrangement under the condition that the incidence angle measured by the first optical sensor arrangement lies within a set interval.
