摘要： An optical absorbance spectrometer including a sample housing configured to hold a sample, a light source configured to emit broadband light into the sample housing, one or more reflectors configured to reflect the light such that the light passes through a sample holding volume of the sample housing multiple times, and a sensor arranged to receive the light from the sample housing, after the reflections. The sensor comprises a plurality of detectors configured to detect the intensity of the received light at multiple different wavelengths.

摘要： An optical module for reading a test region of an assay includes a near-infrared light source for illuminating the test region of the assay with light in a near-infrared spectrum. The optical module also includes an optical detector. The optical detector includes an optical input for receiving light emitted from the test region of the assay and an electrical output. The optical module further includes an electrical signal processor electrically coupled to the electrical output. The optical module additionally includes one or more optical filter arranged in front of the optical input of the optical detector.

摘要： An apparatus for determining the presence or concentration of target molecules comprises: a radiation source; a surface; a waveguide; a detector; and a spectral filter. The radiation source is operable to produce electromagnetic radiation. The surface defines a two dimensional array of receptor sites. The waveguide is arranged to receive the electromagnetic radiation produced by the radiation source, divide the electromagnetic radiation and direct a portion of the electromagnetic radiation to each one of a two dimensional array of receptor sites. The detector comprises a two dimensional array of sensing elements, each sensing element arranged to receive electromagnetic radiation from a different one of the two dimensional array of receptor sites. The spectral filter is provided between the surface and the detector.
