    Abstract: A spectrophotometer for measuring light received from a sample is disclosed. The spectrophotometer includes a measurement head housing a sample and an illumination arrangement having a light source essentially continuous in the visible spectral range, formed by light-emitting diodes. The measurement head includes an illumination channel for each light emitting diode directing the light from each diode at a defined angle of incidence onto a measurement spot on the sample and a collecting arrangement capturing the light originating from the measurement spot. A spectrometer is optically connected to the collecting arrangement for splitting the captured light into its spectral components and for generating corresponding electrical signals. An electronic circuit, constructed for selectively controlling the light emitting diodes, controls the illumination arrangement and the spectrometer and processes the electrical measurement signals. A color densitometer, a variant of a spectorphotometer constructed in accordance with the subject disclosure, is also disclosed.

    Abstract: A method is described that includes measuring, at each of a set of W wavelength bins, a spectral response of at least one region of a sample stained with multiple stains, and determining the concentration of at least one of the stains in the region of the sample based in part on the spectral responses, the wavelength bins being chosen so that a matrix of elements that represent the responses of the stains at the wavelength bin has an inverse for which a mathematical stability is maximum relative to the inverses of other matrices of elements that represent the responses of the stains for other possible sets of wavelength bins.

    Abstract: An arrangement and method for determining the two-dimensional distribution of fundus pigments, particularly of the xanthophyll macular pigment. The arrangement for carrying out the method comprises an illumination unit which illuminates the retina via an illumination beam path directed to the ocular fundus, observation optics located in the observation beam path proceeding from the ocular fundus, an image processing unit, elements for beam deflection and a central controlling and evaluating unit. In the method, a two-dimensional reflection image of the retina is recorded in a selected narrow-band wavelength region. In evaluating this two-dimensional reflection image, site-specific areas are established for determining the optical density and comparison values. The optical density of the fundus pigment at every fundus location is calculated from the negative logarithmic value of the quotient of the intensity value of the reflection image IR(null) at this fundus site to a comparison intensity value of the reflection image IR(null)Comparison. The suggested solution for the objective detection of the two-dimensional distribution of the optical density of the macular pigment xanthophyll is also suitable in principle for determining the distribution of other fundus pigments.

The apparatus comprises at least a radiation source for generating the measuring radiation, and a spectral analyzer for measuring the transmitted radiation, two windows which are disposed opposite one another on the vessel and are transparent to the measuring radiation, and two collimators which are designed to spread the measuring radiation within the range of the measuring section and are disposed opposite one another in front of the windows, characterized in that the collimators are positioned relative to one another in a mounting joined to the vessel and the collimators can, while their relative alignment is maintained, be swung out in parallel from the range of the measuring section in the vessel or be displaced and/or be fixed to the mounting, so that the measuring section bypasses the vessel.

    Abstract: In a detector for spectrometry attached to an integrating sphere, a plurality of detection elements having different spectral sensitivity characteristics is arranged side by side in the same plane on a base, and a side cover is provided such that the detection elements receive light. Thus, the measurement light is directly irradiated to the respective detection elements. Accordingly, the detector for spectrometry has a fast response speed and is excellent in the sensitivity characteristics in a wide wavelength region in the near-infrared area.

    Abstract: An apparatus incorporated within a spectroscopic imaging system, typically a microscope, but also applicable to other image gathering platforms, namely fiberscopes, macrolens imaging systems and telescopes employing a polarizing beam splitting element is disclosed. The apparatus allows simultaneous spectroscopic (i.e. chemical) imaging and rapid acquisition spectroscopy to be performed without the need for moving mechanical parts or time sequenced sampling and without introducing significant optical signal loss or degradation to the spectroscopic imaging capability. In addition, the apparatus affords a more compact design, an improved angular field of view and an improved overall ruggedness of optical design at a lower manufacturing and maintenance cost compared to previous devices.

    CPC classification number: G01J3/08

    Abstract: In a double beam spectrophotometer, a sample beam is irradiated to a large-sized sample in a substantially vertical direction, and the beam upwardly transmitted through the large-sized sample is reflected by a reflecting mirror and sent to an integrating sphere including a detector. A reference beam irradiated parallel to the sample beam is deflected by reflecting mirrors such that the reference beam goes around the large-sized sample, and guided to the integrating sphere. Thus, a holder is not required to correspond to a size or shape of the sample, and measurement position can be freely changed by moving the sample. Also, in case of utilizing a conventional standard sample chamber, movable reflecting mirrors are inserted in the optical paths to transfer the beams to the standard sample chamber.
