a diameter
The line passing through the center of a circle with two endpoints on the circle is the circle's diameter.
A diameter is the length of a chord passing through the center of a circle.
The center of mass of a sphere is its geometric center.
a straight line passing from side to side through the center

The line passing through the center of a circle with two endpoints on the circle is the circle's diameter.
The optical center of a lens is a point on the lens axis where light passing through the lens does not deviate, regardless of the angle of incidence. It is often used as a reference point for optical calculations and design. The optical center is typically at the geometric center of a lens with a symmetrical shape.
