Optical device, image sensor, and method for manufacturing optical device

Abstract

An optical device 1a includes a lens array 10 and a transparent dielectric array 20. The lens array 10 includes a plurality of lenses 11. In the lens array 10, the lenses 11 are arrayed such that the optical axes thereof are substantially parallel to each other. The transparent dielectric array 20 includes a plurality of transparent dielectrics 21. In the transparent dielectric array 20, the transparent dielectrics 21 are arrayed such that the central axes thereof are substantially parallel to each other. The lens array 10 and the transparent dielectric array 20 are arranged such that the optical axes of the lenses 11 and the central axes of the transparent dielectrics 21 are substantially parallel to each other, and that an end surface of the lens array 10 and an end surface of the transparent dielectric array 20 face each other.
