Abstract: A confocal laser scanning microscope for examining a sample has a light source, which generates an illumination light beam, and a scanning unit which deflects the illumination light beam such that it optically scans the sample. A main beam splitter separates the illumination light beam from detection light emerging from the sample. The detection light separated from the illumination light beam passes at least partially through a detection pinhole diaphragm. At least two detector units detect the detection light passing through the detection pinhole diaphragm. An optical element is arranged in the beam direction between the detection pinhole diaphragm and the detector units and splits the detection light into at least two beam bundles and spectrally decomposes it within the beam bundles.

Abstract: A system and method for using near-infrared or short-wave infrared (SWIR) light sources for identification of counterfeit drugs may perform spectroscopy using a super-continuum laser to provide detection in a non-contact and non-destructive manner at stand-off or remote distances with minimal sample preparation. Also, near-infrared or SWIR light may penetrate through plastic containers and packaging, permitting on-line inspection and rapid scanning. The near-infrared or SWIR spectroscopy may also be used to detect illicit drugs and their chemical composition. Moreover, the spectroscopic techniques may also be applied to quality assessment and control in pharmaceutical manufacturing, thus permitting the implementation of smart manufacturing with feedback control. Fiber super-continuum lasers may emit light in the near-infrared or SWIR between approximately 1.4-1.8 microns, 2-2.5 microns, 1.4-2.4 microns, 1-1.8 microns. In particular embodiments, the detection system may be a dispersive spectrometer, a Fourier transform infrared spectrometer, or a hyper-spectral imaging detector or camera.

Abstract: The invention relates to sensors for monitoring a medium comprising at least one electromagnetic radiation source and a detector of electromagnetic radiation, the medium being located in the ray path between the electromagnetic radiation source and the detector. The sensors are characterized by their ease of production. To that end, the electromagnetic radiation source and detector are disposed in at least one housing. Furthermore, the housing comprises two flat wall regions which are arranged at a mutual angle and are transparent to the electromagnetic radiation, such that these wall regions and the medium located thereat form a prism which refracts the electromagnetic radiation. In addition, the detector is at least a one-dimensional sensor comprising photo diodes for the refracted electromagnetic radiation, a spectrum which varies when the medium varies being detectable.
