The optical center of a spherical lens is a point such that If a ray passes through it, then its lens-exiting angle with respect to the optical axis is not deviated from the lens-entering angle. In the right figure, [ 8 ] the points A and B are where parallel lines of radii of curvature R 1 and R 2 meet the lens surfaces.
Atomic, molecular, and optical physics (AMO) is the study of matter–matter and light–matter interactions, at the scale of one or a few atoms [1] and energy scales around several electron volts. [ 2 ] : 1356 [ 3 ] The three areas are closely interrelated.
F A (I) centers have similar properties as regular F centers, whereas F A (II) centers cause two potential wells to form in the excited state due to the repositioning of a halide ion. Similar to the F A is the F B center, which consists of an F center with two neighbouring positive ions replaced by a positive ion of a different kind.
Optical rotation, also known as polarization rotation or circular birefringence, is the rotation of the orientation of the plane of polarization about the optical axis of linearly polarized light as it travels through certain materials. Circular birefringence and circular dichroism are the manifestations of optical activity.
The optical properties of a material define how it interacts with light. The optical properties of matter are studied in optical physics (a subfield of optics ) and applied in materials science . The optical properties of matter include:
The centre of the diaphragm's aperture coincides with the optical axis of the lens system. Most modern cameras use a type of adjustable diaphragm known as an iris diaphragm, and often referred to simply as an iris. See the articles on aperture and f-number for the photographic effect and system of quantification of varying the opening in the ...

Subscripts 1 and 2 refer to initial and final optical media respectively. These ratios are sometimes also used, following simply from other definitions of refractive index, wave phase velocity, and the luminal speed equation:
