What is "spherical aberration" in a curved mirror and what is the reason for it? What can be done to avoid it?

Expert Solution

When light refracts through a lens with a spherical surface, the rays that pass through the outer diameters of the lens will focus at a different point from rays that pass through the center. This causes the resulting image to be blurred. This is called spherical aberration.

The simplest method of avoiding (rather reducing) spherical aberration is to place an aperture, hole or "stop", in front of or after the lens.

Describe the reduction in the spherical aberration for a plano-convex lens for the special case of collimated light (parallel light) focused down to a focal point. Which orientation of the lens gives the least spherical aberration and why? Show ray diagrams Describe how and axial-GRIN lens can further reduce the spherical aberration. Again show a qualitative ray diagram.

A concave spherical mirror with a focal length of 12 cm faces a plane mirror with the optical axis of the spherical mirror perpendicular to the plane mirror. A small object is placed at point P on the optical axis, 11 cm from the plane mirror and 29 cm from the vertex of the spherical mirror. Find the distance from the plane mirror to the three nearest images. (Enter your answers from smallest to largest.) first nearest image second nearest...

A dentist uses a curved mirror to view the back side of teeth on the upper jaw. Suppose she wants an erect image with a magnification of 2.0 when the mirror is 1.2 cm from a tooth. (Treat this problem as though the object and image lie along a straight line.) Part A Use ray tracing to decide whether a concave or convex mirror is needed, and to estimate its focal length. concave? or convex? Part B Use ray tracing...

Spherical mirrors. Object O stands on the central axis of a spherical mirror. For this situation object distance is ps = +19 cm, the type of mirror is concave, and then the distance between the focal point and the mirror is 13 cm (without proper sign). Find (a) the radius of curvature r (including sign), (b) the image distance i, and (c) the lateral magnification m. Also, determine whether the image is (d) real or virtual, (e) inverted from object...
