Abstract:
A hybrid optical element includes: a glass substrate having a first optically functional surface and a second optically functional surface; and a resin layer bonded to the second optically functional surface. The glass substrate further has an outer peripheral surface provided around the first optically functional surface. The outer peripheral surface has a surface roughness Ra of at least 1 μm but not more than 20 μm.
