Abstract There is provided a biometric imaging device configured to be arranged under an at least partially transparent display panel and configured to capture an image of an object in contact with an outer surface of the display panel. The biometric imaging device comprises: an image sensor comprising a photodetector pixel array; a transparent substrate arranged to cover the image sensor; an opaque layer covering an upper surface of the transparent substrate, wherein the opaque layer further comprises a plurality of separate openings; and a plurality of microlenses, each microlens being arranged in alignment with a respective opening of the opaque layer; wherein each microlens is configured to redirect light through the transparent substrate and onto a subarray of pixels in the photodetector pixel array.
