describe
A toric mirror is an optical component with a special design that combines two or more different surface shapes, such as spherical, parabolic, elliptical, or hyperbolic, to achieve specific optical performance. The design of this mirror allows it to be more flexible and efficient in handling light than a single curved mirror, especially in correcting aberrations and improving imaging quality.

Design Principle
The design of multifocal mirrors is based on the complexity of light propagation in optical systems and the impact of different types of aberrations on imaging quality. By combining different surface shapes onto a mirror, multiple aberrations such as spherical aberration, coma, astigmatism, and field curvature can be corrected simultaneously. The flexibility of this design means that multifocal mirrors can be customized to meet specific application requirements, providing better optical performance.
