Abstract
A panoramic lens assembly includes a first lens assembly which includes a first lens group, a first prism and a second lens group, all of which are arranged in order from a first object side to a first image side along a first optical axis. The first lens group is with negative refractive power and includes a first and a second lens. The first prism includes a first incident surface, a first reflective surface and a first exit surface. The second lens group is with positive refractive power and includes a third, a fourth, a fifth, a sixth and a seventh lens. The first lens assembly satisfies: 0.2≤TTL/θ≤0.4, wherein TTLis an interval in mm from an object surface of the first lens to a first image plane along the first optical axis and θis a half maximum field of view in degree for the first lens assembly.
