Abstract:
An alignment device having two angular degrees of freedom is provided. The alignment device is adjustable such that it is suitable for aligning a first apparatus with respect to a second apparatus. The first apparatus may emit one or more of electromagnetic waves, acoustic waves and matter towards the second apparatus and for detection by the second apparatus. The first and second apparatuses may be disposed in a harsh environment such as is found in the vicinity of an industrial process stack. In some embodiments the first apparatus is a laser, preferably a tunable diode laser, and the second apparatus is a receiver incorporating a detector. In these embodiments the apparatuses may be used to perform laser absorption spectroscopy on a process gas flowing through an industrial process stack.

In some aspects, a flow cytometer system is provided that includes beam shaping optics positioned to manipulate a light beam and produce a resulting light beam that irradiates the core stream at the interrogation zone of the flow cell. The beam shaping optics include an acylindrical lens positioned to receive and focus light in a direction of a first axis orthogonal to a direction of light travel, and a cylindrical lens positioned to receive the light output from the acylindrical lens and to focus the light output from the acylindrical lens in a direction of a second axis orthogonal to the first axis and to the direction of light travel.
Abstract:
A device is provided for combining two or more separate components of an optical analysis system, to use common entrance and exit apertures for optical measurements across a measurement space such as a stack, combustion chamber, duct or pipeline, in such way that the optical paths from the respective light sources to detectors are substantially the same, enabling multiple optical measurements over a single optical path or closely aligned optical paths with equivalent ambient conditions such as temperature and pressure distribution and background substance concentrations. The device and a set of interconnectable devices forming a modular system are useful, for example, in absorption spectroscopy, such as for measuring the amount fraction of the chemical constituents of a fluid in a measurement volume.

Abstract:
The present invention relates to a plasmonic structure (10) comprising a substrate and an electro conductor (12) provided in or on the substrate (11). The electro conductor (12) comprises a first part (13) configured to provide a first series of plasmon resonance modes (for incident radiation of a first wavelength) and a second part (14) configured to provide a second series of plasmon resonance modes (for incident radiation of a second wavelength). The first and second part are functionally connected in a linkage region (15), where the electro conductor (12) is shaped such as to form a capacitive gap (16). The electro conductor (12) is furthermore configured to direct radiation incident on the plasmonic structure of a first wavelength predominantly toward a first direction and to direct radiation incident on the plasmonic structure of a second wavelength predominantly toward a second direction, in which the first direction and the second direction are separated by an angle of at least 60°.
Abstract:
According to an example, an apparatus for performing spectroscopy includes a parabolic reflector and a plurality of surface-enhanced Raman spectroscopy (SERS) elements spaced from the parabolic reflector and positioned substantially at a focal point of the parabolic reflector. The parabolic reflector is to reflect Raman scattered light emitted from molecules in a near field generated by the plurality of SERS elements to substantially increase the flux of the Raman scattered light emitted out of the apparatus.
