Abstract
A 4K high-resolution panoramic annular optical system includes a panoramic annular lens head unit, a subsequent lens group, and a 4K sensor (SE) that is coaxially installed. The panoramic annular lens head unit includes a first lens (PALIPAL) and a second lens (PAL). The subsequent lens group includes a third lens (RL), a fourth lens (RL), a fifth lens (RL), a sixth lens (RL), a seventh lens (RL), an eighth lens (RL), and a ninth lens (RL) that are arranged in order from an object plane to an image plane. The first lens (PAL) and the fifth lens (RL) are meniscus glass lenses with positive refractive power. The six lens (RL) and the ninth lens (RL) are meniscus glass lenses with negative refractive power, and the second lens (PAL), the fourth lens (RL), the seventh lens (RL), and the eighth lens (RL) are biconvex lenses with positive refractive power.
