Document Type and Number:
WIPO Patent Application WO/2024/009538
Kind Code:
A1
Abstract:
This optical device 1a comprises a lens array 10 and a transparent dielectric array 20. The lens array 10 includes a plurality of lenses 11. The plurality of lenses 11 in the lens array 10 are arranged so that the optical axes thereof are substantially parallel to each other. The transparent dielectric array 20 includes a plurality of transparent dielectrics 21. The plurality of transparent dielectrics 21 in the transparent dielectric array 20 are arranged so that the center axes thereof are substantially parallel to each other. The lens array 10 and the transparent dielectric array 20 are disposed so that the optical axes of the lenses 11 and the center axes of the transparent dielectrics 21 are substantially parallel, and an end surface of the lens array 10 and an end surface of the transparent dielectric array 20 face each other.
