An optical device for the quantitative determination of the concentration of at least one analyte in a liquid sample comprises a housing () defining a first chamber () and a second chamber (). A sample port () is defined in the first chamber (). The sample port () receives light from a plurality of test regions of an assay device when the optical device is engaged with the assay device. The optical device further comprises a plurality of optical detectors () provided in the second chamber () and a mask member () interposed between the first chamber () and the second chamber () and having an aperture () defined therein and configured to direct light from the sample port () onto the optical detectors ().

Optical device for quantitative determination of the concentration of an analyte in a liquid sample comprising a mask member between first and second chambers

There is provided a device, such as a microfluidic device, for performing an assay including: a substrate comprising a channel, such as a microfluidic channel; at least one optical element having an input port arranged to be optically coupled to a light source; an output port optically coupled to at least a portion of the channel; and a light guide portion optically connecting the input port and output port; and a detection port optically coupled to said at least a portion of the channel. The device provides an improved geometry which addresses problems related to traditional orthogonal detection arrangements and in-line detection systems.

Optical device for performing an assay

A detector apparatus and method for detecting radiation emitted from a target comprising: a first transmissive polarizer () for polarizing radiation incident on the target; a second transmissive polarizer () for polarizing the radiation emitted from the target () and absorbing any remaining light polarized by the first polarizer; and at least one reflective polarizer () arranged between the first and second transmissive polarizers.
