An apparatus for determining an index of insect biodiversity comprises a plurality of optical insect sensor devices configured to be individually positioned within a geographic area and a data processing system. Each sensor device is configured to monitor insect activity within a detection volume by detecting light from the detection volume, and to output detector data indicative of one or more optically detected attributes associated with respective detected insect detection events. Each insect detection event is indicative of one or more insects being present in the detection volume. The data processing system is configured to receive detector data from respective ones of the plurality of optical insect sensor devices. The detector data is indicative of one or more optically detected attributes associated with respective detected insect detection events. The system computes, from the received detector data, an index of insect biodiversity indicative of insect biodiversity within the geographic area.

A method for preparing a sample of organic material for laser induced breakdown spectroscopy (LIBS) may include obtaining granular organic material, forming a portion of the granular organic material into a sample pellet, and searing the organic material. The searing may include searing only an exposed end surface of the sample pellet on which LIBS analysis is to be performed. The method may include pressing the seared sample pellet to consolidate the material comprising the seared end surface.

Method for preparing a sample for laser induced breakdown spectroscopy

A Laser Induced Breakdown Spectrocopy (LIBS) system for the analysis of a sample pellet of a consolidated granular material retained in a tubular container may include a laser source configured to emit a pulsed laser beam towards an exposed surface of the sample pellet; and a sample station configured to hold the cylindrical tubular container in one or more orientations to present an exposed surface of the sample pellet towards the pulsed laser beam. The sample station may induce linear movement of the sample pellet along an axis and to expose a portion of the outer side surface of the sample pellet previously constrained through contact with an inner surface of the cylindrical tubular container. The sample station may induce rotational motion of the outer side surface of the sample pellet around the movement axis to present the portion of the outer side surface as the exposed surface.

System for and method of performing laser induced breakdown spectroscopy

A system () for determining properties of a sample () comprises a LIBS detector () and an infra-red absorption detector () for interrogating a sample () to generate LIBS spectral data and infra-red absorption spectral data respectively; and a data processor () adapted to apply at least one chemometric prediction model, each constructed to link, preferably quantitatively link, features of both LIBS and absorption spectral data to a different specific property of the sample, to a combined dataset derived from at least portions of both the LIBS and the absorption data to generate therefrom a determination, preferably a quantitative determination, of the specific property linked by that model.

System for and method of combined LIBS and IR absorption spectroscopy investigations

An optical spectrometer may include: an adjustable sampling space having two opposing side-walls between which in use a sample for analysis is charged and in at least one of which is formed an optical interface translucent to optical energy emitted by an optical energy source; an actuator mechanically coupled to one or both of the opposing side-walls and configured to operate in response to a command signal applied thereto to effect relative movement of the opposing side-walls; and/or an optical position sensor configured to detect interference fringes generated by the optical energy traversing a distance between the side-walls a plurality of times, having passed through the at least one optical interface, and configured to generate the command signal in dependence thereof. The adjustable sampling space may be brought into an analysis position at which the side-walls are relatively inclined to form a wedge shape.

Optical spectrometers

An optical component including an acceptance fiber, e.g. a photonic crystal fiber, for propagation of pump and signal light, a number of pump delivery fibers and a reflector element that reflects pump light from the pump delivery fibers into the acceptance fiber. An optical component includes a) a first fiber having a pump core with an NA1, and a first fiber end; b) a number of second fibers surrounding the pump core of the first fiber, at least one of the second fibers has a pump core with an NA2 that is smaller than NA1, the number of second fibers each having a second fiber end; and c) a reflector element having an end-facet with a predetermined profile for reflecting light from at least one of the second fiber ends into the pump core of the first fiber.
