Abstract: An optical module (100) for reading a test region of an assay. The optical module comprises: a first light source (101) for illuminating the test region of the assay; an optical detector (103), comprising an optical input for receiving light emitted from the test region and an electrical output; a substrate (104) for mounting the first light source (101) and the optical detector (103); and a housing (105) comprising: a first opening (106) for providing a first optical path from the first light source (101) to the test region (103); wherein the housing (105) and the substrate (104) enclose and positionally align the first source (101) and the optical detector (103) relative to the first opening (106). The housing (105) may comprise one or more legs (108), such as a flexible hook portion which secures the housing (105) to the substrate (104) with a snap-fit engagement, extending from a first and/or second outer surface of the housing (105) in a vertical direction. Beneficially, the snap-fit engagement provided by the flexible hook portion allows the housing to be aligned and secured without the need to use glue or for example a screw and thread that can be difficult to control and/or risks misalignment of the housing.

Abstract: A lateral flow test device includes a test chamber having a detection aperture. The lateral flow test device also includes an optical detector configured to receive light from an assay test strip through the detection aperture when the assay test strip is provided in the test chamber. The test chamber is configured for manual feed of at least a portion of the assay test strip passed the detection aperture. The optical detector is configured to detect one or more tracking features associated with the assay test strip so as to determine when at least a test line on the assay test strip is detectable through the detection aperture.

Abstract: An optical absorbance spectrometer includes a sample housing, a light source and a spectral sensor. The sample housing comprises at least two sample cells configured to hold a sample, respectively, and includes an optical waveguide which is configured to guide light from an input side, through the sample cells, to an output side. The light source is operable to emit broadband light and is connected to the input side to couple emitted light into the optical waveguide. The spectral sensor is connected to the output side and operable to receive light from the optical waveguide and to detect the intensity of the received light at multiple wavelengths.

Abstract: It is proposed to use self-mixing interferometry for determining an absorption. The monitoring device for use in lateral flow testing for detecting presence or amount of an analyte in a liquid includes a housing, the housing including a carrier holder for holding a carrier for transport of the liquid; at least a first light source which is a resonant-cavity light source having a cavity; and an evaluation unit, operationally connected to at least the first light source for detecting a measurement signal. The first light source is structured and arranged to illuminate with light a test range in a test area of a carrier held in the carrier holder; and to couple back into the cavity of the first light source a portion of the light coming back from the test range.
