  • Patent number: 11684266
    Abstract: A probe comprising a body portion and a tip portion. The body portion comprises: a first mounting portion comprising a plurality of first carriers, each first carrier being arranged to support an elongate first waveguide, the first carriers being disposed in an equiangular arrangement around a longitudinal axis of the body portion; a plurality of first waveguides, each first waveguide being supported in a respective one of the plurality of first carriers; and a body end fitting at which first ends of the first waveguides are supported in the equiangular arrangement around the longitudinal axis of the body portion such that the first waveguides can transmit electromagnetic radiation signals from an energy source to the body end fitting and/or transmit electromagnetic radiation signals from the body end fitting to a receiver.

  • Patent number: 11617512
    Abstract: A probe, such as a spectroscopic probe, for enabling a fluid or tissue sample to be tested in situ. The probe includes a conduit, such as a hypodermic needle, that can be inserted into a test subject and a wave coupling arranged to direct electromagnetic radiation, such as light, from an energy source to the sample and/or from the sample to a receiver for analysis. The receiver may comprise a Raman spectroscope. The probe may include a carriage that can be used to move at least some of the optical coupling towards and away from the insertion tip of the conduit. The probe may include a pressure modifier that can be used to draw fluid into or expel fluid from the conduit.

  • Patent number: 9772479
    Abstract: An optical device includes a first sub-assembly having an input lens for collimating illuminating light and having an optical axis. The first sub-assembly also has an output lens for focusing collimated light received from a sample, the output lens having an optical axis which is offset and substantially parallel with the optical axis of the input lens, and further includes a first support piece which houses and supports the input lens and the output lens. The optical device also includes a second sub-assembly having an input filter for filtering the collimated illuminating light, an output filter for filtering the collimated light received from the sample, and a second support piece which houses and supports the input filter and the output filter. The first and second support pieces are joined together by a liquid-tight joint.
