    Abstract: A miniature readhead for a photometric diagnostic instrument includes a housing of hand-held form factor, configured for receiving reagent sample media therein. The sample media has a plurality of test areas configured to react with, and change color, according to an amount of an analyte in a sample. The holder is sized and shaped for forming an indexed fit with the sample media and includes an array of light sources coupled to the housing, each of the light sources configured to emit light onto a respective one of the test areas. An array of chambers respectively containing an array of light detectors, is configured to enable each of the light detectors to receive diffuse, non-specular reflections of the light from the test areas, while substantially preventing the light detectors from receiving specular reflections of the light.

    Abstract: The invention relates to a device and method for measuring the properties of a surface. The device comprises means for producing illuminating light, which means are arranged to aim the illuminating light at the surface to be measured using at least two different wavelengths and at least two different angles, as well as means for directing the light reflected or scattered from the surface to a detector, in order to create an image of the surface to be measured. The device according to the invention further comprises at least one reference surface, the contents of which can be placed in the vicinity of the surface to be measured, in such a way that the illuminating light is also aimed at the reference surface and the light reflected or scattered from the reference surface can also be directed to the detector. The invention makes possible excellent measurement precision and repeatability, using a simple device construction with low production costs.
