An image sensor includes a plurality of photodiodes arranged in an array and disposed in a semiconductor material with pinning wells disposed between individual photodiodes in the plurality of photodiodes. The image sensor also includes a microlens layer. The microlens layer is disposed proximate to the semiconductor material and is optically aligned with the plurality of photodiodes. A spacer layer disposed between the semiconductor material and the microlens layer. The spacer layer has a concave cross-sectional profile across the array, and the microlens layer is conformal with the concave cross-sectional profile of the spacer layer.
