Optics radius of curvature

WebMar 5, 2024 · The easiest way to understand the phenomenon of astigmatism is to imagine a lens (or mirror) whose surfaces are not exactly spherical but for which the radius of curvature (and hence focal length) in one plane is different from the radius of curvature in a plane at right angles to the first. Web2) A spherical mirror is placed on the optics bench as shown in Figure 10.3-2. Once a clear image is located, the object position is recorded to be (10.0+0.05)cm, the image position is (68.1+1.0)cm, and the mirror position is (80.0+0.05)cm A) Calculate the radius of curvature of the spherical mirror (including uncertainty).

Radius of curvature (ROC) has specific meaning and sign convention in optical design. A spherical lens or mirror surface has a center of curvature located either along or decentered from the system local optical axis. The vertex of the lens surface is located on the local optical axis. The distance from the vertex to the center of curvature is the radius of curvature of the surface.
