  • Wide-aperture spherical primary mirror off-axis afocal optical system
    Patent number: 11906718
    Abstract: The invention provides a wide-aperture spherical primary mirror off-axis afocal optical system, including a primary mirror, a secondary mirror and an aberration compensation mirror group. The primary mirror is a spherical reflector, the secondary mirror are higher-order aspherical reflectors. The primary mirror and the secondary mirror form an off-axis two-mirror system to compress the beam aperture. The aberration compensation mirror group is a coaxial reflective system that is used off-axis. The aberration compensation mirror group has focal power to produce compensation aberrations. The incident beam passes through and is reflected by the primary mirror and secondary mirror sequentially and enters the aberration compensation mirror group thereafter.
