    Abstract: A light source for near-infrared transmission and reflection spectroscopy can be constructed from a combination of a high power blue or blue-green light emitting diode (LED) and a phosphor element based on an inorganic material. The phosphor element absorbs the LED light and, in response to the LED excitation, emits luminescence that continuously covers the 700-1050 nm range. One possible material that can be used for such a near-infrared emitting phosphor element is a single crystal rod of Ti+3 doped Sapphire. An alternative near-infrared emitting phosphor material is a disk or rectangular shaped composite of Ti+3 doped Sapphire powder embedded in a clear optical epoxy or silicone encapsulant. Such a combination of a blue LED for excitation of a phosphor element that emits in a broad wavelength band has been widely used in white LEDs where the emission is in the 400-700 nm range.

    Abstract: An optical device is provided that includes a converging lens device, a transmitting optical fiber, a sample holder, and a receiving optical fiber. The converging lens device focuses light onto the transmitting optical fiber, which receives the focused light through an entrance face and transmits the light from an exit face, through a sample, and onto the receiving optical fiber. The sample holder holds the sample for analysis. The receiving optical fiber receives the light through an entrance face of the receiving optical fiber after transmission through the sample. The converging lens device is positioned to focus the light onto the entrance face of the transmitting optical fiber such that a half-angle of the angular distribution of the focused light that reaches the entrance face of the transmitting optical fiber is selected to underfill an entrance aperture of the entrance face of the receiving optical fiber in both a spatial dimension and an angular dimension.

    Abstract: The invention relates to a device for measuring fluorescent radiation emitted by biological substances, comprising a light source (18), a capturing unit (20), an evaluation unit (28) that is coupled to the capturing unit (20), at least one emission fibre (14) that is coupled to the light source (18), and at least one detection fibre (16) that is coupled to the capturing unit (20). Said emission fibre (14) guides excitation radiation to the biological substrate and the detection fibre (16) receives fluorescent radiation excited on the biological substance and guides it to the evaluation unit (28). According to the invention, the capturing unit (20) comprises a semi-conductor sensor arrangement (62) in which at least three sensors that are arranged inside a surface and that detect fluorescent radiation emitted by the biological substance in wave length areas that are separate from each other, are arranged. Data sets of at least two different reference measurements on at least two different biological substances are stored in the evaluation unit (28) that compares the measured measurement values to the stored data sets and issues a result relating to the pathological attacks of the examined biological substances and/or relating to the type of examined, biological substances.

    Abstract: A spectrophotometer has a first photodetector (24) and a second photodetector (25) which is displaced spatially from the first photodetector in the direction of increasing wavelength in the spectrum. At any given time the second photodetector receives light at a wavelength which is substantially greater than that being received simultaneously by the first photodetector at that time. The first photodetector has a first range of wavelengths over which it is operable and a first upper operating limit, and the second photodetector has a second range of wavelengths over which it is operable and a second upper operating limit, the second range overlapping the first range and the second upper operating limit being greater than the first upper operating limit. Thus the range of operation is extended, and data in two different ranges is processed simultaneously. The spectrophotometer comprises a housing (1) containing a light source (11), a monochromator (15, 16, 18) and the photodetectors, there being a fibre optic connected to a probe (2) for transmitting light from the light source to a sample to be analysed and receiving light from the sample. Optical components are mounted to a chassis (26) of the housing rigidly, the chassis being connected to the housing by shock absorbing mounts (28, 29). The light source is mounted to the housing by means of an adjuster (24) providing for adjustment laterally with respect to the optical axis of the light source.
