describe

A freeform lens is a type of non spherical lens whose surface is shaped like a freeform surface. The optical performance of free-form surface lenses is superior to spherical lenses, which can improve image distortion and clarity.

Freeform lenses are commonly used in optical systems such as camera lenses, optical instruments, and medical imaging. Its manufacturing technology is relatively complex, usually using techniques such as laser cutting, grinding, or polishing.

The optical performance of free-form surface lenses is related to the material.
