MICROLENS ARRAY AND IMAGING ELEMENT PACKAGE

摘要

A microlens array (10) is provided with a glass substrate (1) and a plurality of microlenses (11) arranged in an array and provided on at least one side of the glass substrate (1), and is characterized in that each of the plurality of microlenses (11) is configured to cause light incident on the respective microlens (11) to be received by a plurality of pixels of an imaging element, and the difference between the coefficient of linear expansion of the glass substrate (1) and the coefficient of linear expansion of an imaging element substrate (4) on which a pixel array is formed, or a member of a package (6) joined to the imaging element substrate (4), is 8 × 10-6 (/K) or less. By this microlens array, misalignment between the pixel pitch of the imaging element and the lens pitch is prevented in an imaging device that uses a combination of the microlens array and an imaging element pixel array.
