Abstract
An image capturing device includes a cover plate, a sensing module, a frame body, a first adhesive layer, and a second adhesive layer is provided. The sensing module includes a sensor and a light collimator. The light collimator is disposed between the cover plate and the sensor. The light collimator includes a plurality of light collimating units. Each of the light collimating units includes at least one fiber and a plurality of light absorbing columns. The light absorbing columns are disposed parallel to the at least one fiber and surround the at least one fiber. A thickness of the light collimator is T. A distance between two light absorbing columns farthest from each other among the light absorbing columns in each of the light collimating units is D. A numerical aperture of the at least one fiber is NA, NA≤0.7, and D≤T×tan[sin−1(NA)].
