Excerpt from Elementary Treatise on Optics: Containing All the Requisite Propositions Carried to First Approximations; With the Construction of Optical Instruments, for the Use of Junior University Students

In the present First Part of Geometrical Optics, the theory of optical instruments will be discussed, by taking the propositions to first approximations only; and in the Second Part the proposi tions will be discussed to second approximations, and the more corrected forms of some of the instruments treated of. This method involves the advantages of a more elementary treatise in the First Part, and a higher one in combining the two Parts.

Excerpt from Elementary Treatise on Optics: Containing All the Requisite Propositions Carried to First Approximations; With the Construction of Optical Instruments, for the Use of Junior University Students

The science of Optics is that, in which the properties and laws of light and vision are treated of.

It is subdivided into Geometrical Optics and Physical Optics: the former comprehending the application of certain simple determined properties or laws of light to the theory of optical instruments, and the structure of the eye; and the latter treating of the phenomena arising from properties which are connected with the more intimate nature of light, as interference, polarization, &c.

In the present First Part of Geometrical Optics, the theory of optical instruments will be discussed, by taking the propositions to first approximations only; and in the Second Part the propositions will be discussed to second approximations, and the more corrected forms of some of the instruments treated of. This method involves the advantages of a more elementary treatise in the First Part, and a higher one in combining the two Parts.

Our whole perception and knowledge of the existence of light depends on the eye, as the organ of the sense of vision; and through it we receive the wonderful perception of the forms, colours, positions, &c. of distant objects, by the light coming from them. Every portion of space through which light traverses, is in Optics called a medium. Thus a vacuum, the atmosphere, transparent liquids and solids, are called media.
