Document Type and Number:
WIPO Patent Application WO/2023/177029
Kind Code:
A1
Abstract:
An off-axis lens assembly having an incident angle according to the present invention comprises: a body; and a first off-axis lens, a second off-axis lens, and an on-axis lens attached to the body. The body is provided with a reference surface, and comprises a first through-hole which is formed to have an incident angle that is inclined with respect to the reference surface, a second through-hole which is formed to have a reflective angle corresponding to the incident angle, to be inclined with respect to the reference surface, and a third through-hole formed perpendicularly to the reference surface. The central axis of the first through-hole, the central axis of the second through-hole, and the central axis of the third through-hole are aligned on the same plane that is perpendicular to the reference surface, and are formed to cross one another at one point. The first off-axis lens is attached to the first through-hole of the body, the second off-axis lens is attached to the second through-hole of the body, and the on-axis lens is attached to the third through-hole. Also, the first off-axis lens and the second off-axis lens can adjust the inclination angles with respect to the central axis of the first and second through-holes to which the first and second off-axis lenses are attached, and the first off-axis lens, the second off-axis lens, and the on-axis lens can be moved up and down along the central axis of the first to third through-holes to which the first and second off-axis lenses and the on-axis lens are respectively attached.
