Ophthalmic lenses, dioptric formulae for combined cylindrical lenses : the prism-dioptry, and other optical papers (1900)
Prentice, Charles Frederick, b. 1854 · Philadelphia : Keystone · leaf 115
feasible, as well as suited to therequirements of optometrical practice, is presented. IjQi abc, Fig. 1, represent a prism, with the ray z incident perpendicularly to ab, and we shall have dv as the deflection accruing from the refraction at e. Similarly, ^F will represent the deflection arising… … Fig. 1. By adopting one meter as the distance of the point e from the plane PP^^in which the amplitudes of deflection dv and dV are measured, we shallhave de-=\y when (1) d,e It is further evident that the greater the refractive power of the prism,ihe greater will be its correlative deflection in…
