The centre of curvature of thelensface (C): It is the centre of the sphere, where this face is a part of it. eg. C1& C2.The lens has two centres of curvature because it has two spherical surfaces, each surface has a center. The optical centre of the lens (P)...
PURPOSE:To let the size or imaging point position of image be proportional to scanning angles by using the planoconvex lens which satisfies the specific conditions and in which the center of the exit pupil becomes nearly equal to the center of the curvature of the convex face. CONSTITUTION:If...
Convex and concave lens - a lens with one side convex and one side concave The connection between the centers of curvature on both sides is called the principal axis.The point O in the center is called the optical center.The same side of the projected ray intersects point F, and the refr...
For a double convex lens the radius R1 ispositive since it is measured from the front surface and extends right to the center of curvature. The radius R2 is negative since it extends left from the second surface (Source). What is the difference between convex and plano-convex lens?
If the radii of curvature of the two surfaces are large compared to the thickness of the lens, then the lens may be considered to be a “thin lens” for which the following equations are valid. Sign in to download full-size image Figure 4.8.A1.3. Spherical lenses focus parallel incident...

The larger the focal length, the more convex the surface of the convex mirror, and the better the light-gathering function. Concave lens principle: The line connecting the centers of curvature of the two sides is called the main axis, and the point in the center is called t...
