SUBSTRATE FOR EVALUATING MICROLENS

摘要

PROBLEM TO BE SOLVED: To provide a substrate for evaluating a microlens capable of precisely evaluating the light condensing state of the microlens.

SOLUTION: The problem is solved by providing the substrate for evaluating the microlens which has a transparent substrate, a light shielding layer formed on the transparent substrate, a focal length adjusting layer formed on the light shielding layer and the microlens formed on the focal length adjusting layer. On the light shielding layer, a measuring opening is formed at a position through which light condensed by the microlens is passed in the emission of light to the microlens.
