A microlens in radiography in providing healthcare services, including medical and dental fields. The microlens preferably is included as a component of a detector. The detector preferably comprises a converter, a plate, a filter, the microlens, and a collector including photosensitive areas. Low light images are received at the converter and transmitted directly or through the plate to the filter and then to the microlens. The microlens collects, refines and focuses the low light image that would have otherwise fallen onto the non-sensitive areas of the collector, thereby enabling low light detection efficiency at the sensitive areas, and thereby increasing the collector fill factor and quantum efficiency.
