Abstract:
A disposable photometric measurement tip comprising a polymer tip, the polymer tip having a capillary filling channel, the capillary filing channel having an opening at a distal end of the polymer tip, a wave guide channel acting as an optical input coupling and a wave guide channel acting as an optical output coupling, each of the wave guide channels having an opening at a proximal end of the polymer tip wherein the capillary filling channel, the wave guide channel acting as an optical input coupling and the wave guide channel acting as an optical output coupling are connected to each other.
Abstract:
The invention relates to a lens main part (10) for a spectrometer for mounting other components (18, 24, 28) of a spectrometer, the lens main part being produced as a sandwich construction from at least three flat elements (12, 14, 16) arranged one on top of the other and interconnected, in particular bonded, each of said flat elements (12, 14, 16) having a low coefficient of thermal expansion which is substantially isotropic, at least on one isotropic plane. The flat elements (12, 14, 16) are arranged on top of one another and interconnected such that their isotropic planes run substantially parallel to one another.
Abstract:
A modular device includes base and color sensing portions. The color sensing portion has a face, a controlled light source offset from the face to define an interior, the face configured to engage a target surface about a perimeter of the device housing wherein ambient light is restricted from entering the interior. A color sensor receives light reflected from the target surface and generates output signals representative of a surface color. The base portion communicates with the color sensor and a user device having a hosted program which generates a user interface enabling users to provide control input for the color sensor. The program further receives the output signals from the color sensing device and displays a first image of the detected color, and displays a second image of a user-selected color beside the first image. Color data values are further displayed corresponding to the difference between displayed colors.
Abstract:
A method of identifying an underwater material in an underwater scene comprises analysing a specimen of a material extracted from a body of water using a hyperspectral imager (58) to determine a hyperspectral profile of the material. The hyperspectral profile is stored. An image is taken of an underwater scene in a body of water (22) using the hyperspectral imager (58) or a further hyperspectral imager. An observed hyperspectral profile is generated from the scene. The observed hyperspectral profile is compared with the stored hyperspectral profile to identify the material in the underwater scene. A positive identification is recorded when the comparison is sufficiently close.
Abstract:
A system is provided for performing filter-based and monochromator-based measurements. The system includes a light source (250) and a plurality of detectors (112, 114). An excitation monochromator (130) outputs a selected wavelength component of the excitation light. Emitted light from a sample follows a selected emission optical path. An emission monochromator (132) outputs a selected wavelength component of the emitted light when part of the selected path. An interface cartridge (104) includes emission light ports positioned to direct the emitted light from the sample along a corresponding optical path. The interface cartridge aligns a selected optical path with the main measurement optical axis. A movable sliding switch mechanism (120) provides optical channels corresponding to positions on the sliding switch mechanism to complete a selected emission optical path. The position on the sliding switch mechanism is selected by moving the sliding switch mechanism to align the optical channel for the position with the main measurement optical axis.
