Equal thickness off-axis parabolic mirror

Document

Equal thickness off-axis parabolic mirror


describe

Off axis parabolic mirror is a type of non spherical lens with a parabolic surface shape. The focal position of an off-axis parabolic mirror does not coincide with the incident axis of the light, so it is also known as an off-axis lens.

The optical performance of off-axis parabolic mirrors is superior to spherical lenses, which can improve image distortion and clarity. It is commonly used in optical systems such as camera lenses, optical instruments, and medical imaging.

The manufacturing technology of off-axis parabolic mirrors is relatively complex because their surface shape is not spherical and traditional spherical lens manufacturing methods cannot be used. The manufacturing of off-axis parabolic mirrors usually uses techniques such as laser cutting, grinding, or polishing.
