Abstract
A lens array module includes a light incident surface, a light emitting surface opposite to the light incident surface, and a plurality of first and second lens surfaces. The first lens surfaces are arranged on the light incident surface to form into an array. The second lens surfaces are arranged on the light emitting surface to form into an array. The center of curvature of each of the first lens surfaces located at two opposite sides of a first reference point on the light incident surface deviates away from the first reference point in a direction parallel to a first reference axis, and the center of curvature of each of the second lens surfaces located at two opposite sides of a second reference point on the light emitting surface deviates toward the second reference point in a direction parallel to the first reference axis. A projection apparatus is also provided.
