Cylindrical Lens
2 year ago
These mirrors have a cylindrical shape, meaning that their curvature is constant along one axis and flat along the other axis. The curved surface of the mirror is concave, which means that it curves inward towards the center of the mirror.
Concave cylindrical mirrors are used in various optical systems and applications. One common use is in laser diodes, where they are used to focus and shape the laser beam. They can also be used in optical sensors, barcode scanners, and other imaging systems.
The focal length of a concave cylindrical mirror is determined by its curvature and the refractive index of the medium surrounding the mirror. The focal length is the distance from the mirror at which parallel rays of light will converge or diverge after reflection.
One important property of concave cylindrical mirrors is that they can produce magnified or reduced images, depending on the position and orientation of the object relative to the mirror. When an object is placed closer to the mirror than its focal length, a magnified virtual image is formed. When the object is placed farther away than the focal length, a reduced real image is formed.
Overall, concave cylindrical mirrors have unique properties that make them useful in various optical systems and applications. Their curved surface and specific shape allow for specific focusing and imaging capabilities.
