Off Axis Parabolic Mirrors
Parabolic Mirrors are used to direct and focus all the incoming collimated light into a single focal point due to the surface shape parabola. It’s applicable when there is a need to either collimate or focus the beam and when the beam divergence is small. There are useful for telescopes, retroreflectors, fiber collimators, spectroscopy, lighting and solar applications.

Parabolic mirrors are a type of curved mirror that has a parabolic shape. The parabolic shape allows all incoming parallel rays of light to be reflected to a single focal point, or the focus, located on the axis of symmetry of the parabola.
Parabolic mirrors work by reflecting light waves that strike their surface in a specific way due to their parabolic shape. When light waves hit the curved surface of a parabolic mirror, they are reflected in a way that all the rays parallel to its axis converge to a single point known as the focus. This is because the shape of the parabolic mirror causes each ray of light to be reflected at an angle that is dependent on its distance from the axis of the mirror.
The parabolic shape of the mirror ensures that all incoming parallel rays of light are reflected toward the focal point, while rays coming from other angles are reflected in a way that they miss the focal point. This is why parabolic mirrors are often used in devices that require high-quality and precisely focused beams of light, such as telescopes, satellite dishes, and laser reflectors.
