Abstract:
1. A lens assembly comprising: a first lens including a first optically active portion, a first optically inactive portion surrounding the first optically active portion, and a first optical axis, the first optically inactive portion comprising a first inclined surface inclined relative to the first optical axis; and a second lens including a second optically active portion, a second optically inactive portion, and a second optical axis, the second optically inactive portion comprising a second inclined surface inclined relative to the second optical axis, the second lens being coupled to the first lens, wherein the first inclined surface is in contact with the second inclined surface, a gap is maintained between the second optically inactive portion of the second lens and the first optically inactive portion of the first lens, and a distance between the first optically inactive portion and the second optically inactive portion at the gap is in the range from about 5 μm to about 100 μm.
