Abstract:
The invention relates to a device (10) for the simultaneous detection of radiation of different wavelength, comprising a number of base modules arranged one on top of the other, an optical module (16) and an electronic module. One device each for reflecting and/or deflecting radiation of a determined wavelength range is provided in said base modules. The light-detecting elements are associated with one of the devices each. The invention further relates to a base module, to a charging unit, to a method for adjusting the device (10) and to the use of the inventive device (10).
Abstract:
A protective sheath having a closed end and an open end is sized to receive a hand held spectrometer. The spectrometer can be placed in the sheath to calibrate the spectrometer and to measure samples. In a calibration orientation, an optical head of the spectrometer can be oriented toward the closed end of the sheath where a calibration material is located. In a measurement orientation, the optical head of the spectrometer can be oriented toward the open end of the sheath in order to measure a sample. To change the orientation, the spectrometer can be removed from the sheath container and placed in the sheath container with the calibration orientation or the measurement orientation. Accessory container covers can be provided and placed on the open end of the sheath with samples placed therein in order to provide improved measurements.
Abstract:
A lighting module with variable colors (1, 2) includes an elastic portion (11), a pressure sensor (12), a color detecting unit (13), and a light emitting unit (14). The elastic portion has an internal space. By applying a force (F), the elastic portion can be deformed so as to generate a pressure change of the internal space. The pressure sensor is coupled to the internal space of the elastic portion, and detects the pressure change of the internal space to output a color transformation signal (S 1 ). The color detecting unit is coupled to the pressure sensor. The color detecting unit receives the color transformation signal and is initiated based on the color transformation signal for detecting a color of a target to generate a color signal (S 2 ). The light emitting unit is disposed in the elastic portion, and emits a light corresponding to the color signal. In addition, a lamp (L) with the lighting module with variable colors is also disclosed.
Abstract:
The invention relates to a sensor for a spectrometer, comprising optical means onto which an excitation light source beam is directed and from which a target beam is emitted towards a sample to be analysed. The invention is characterised in that the optical means can move, thereby enabling the direction of the target beam to be varied.
Abstract:
The disclosure relates to a portable system for obtaining a spatially accurate wavelength-resolved image of a sample having a first and a second spatial dimension that can be used for the detection of hazardous agents by irradiating a sample with light, forming an image of all or part of the sample using Raman shifted light from the sample, and analyzing the Raman shifted light for patterns characteristic of one or more hazardous agents.
Abstract:
The present disclosure provides for a device, as well as a system and method associated therewith, for, among other things, providing: (i) up to five distinct measurement angles along with an illumination reference channel; (ii) a plurality of illumination sources that provide a focused beam of illumination at specific desired angles of incidence to a sample under target; (iii) a shutter mechanism incorporating a calibration transfer standard; (iv) an internal optical system that is operatively associated with a gimbaled structure suitable to allow vertical and angular conformity to a target sample; and (v) a handheld and operated enclosure incorporating a user interface with a visual display unit complete with interactive navigation means and an activation switch, and a number of surface detecting contact elements operatively associated with the optical system and shutter mechanism.

Abstract:
The disclosure generally relates to a method and apparatus for multi-wavelength imaging spectrometer. More specifically, in one embodiment, the disclosure relates to an optical filter for passing photons therethrough. The filter includes a first filter stage and a second filter stage. The first filter stage may include a first retarder element (450) and a first liquid crystal cell (455). The first element may include an input face and an output face. One of the first element faces is not oriented substantially normal to the trajectory of photons passing through the filter.
