`
`PERFORMANCE DIAGRAMS
`
`There is considerable value in having an approximate idea of the performance of an
`optical system, for which constructional data has been published. It enables a judgment
`to be made as to whether further work should be carried on, using these data as a
`starting point.
`In order
`For this reason the performance diagrams are given in thefollowing pages.
`to enable a rapid scan to be accomplished, a sketch of each design has been included
`with the performance curves.
`In this way it is a comparatively simple matter to pick
`out possible candidates, in terms of complexity, within each group.
`With one exception,
`to be noted below,
`the constructional diagrams have been
`draWn with the long conjugate of the lens on the left hand side, so that in standard use
`the light can be taken as going through the lens from left to right. The one exception
`is for the section on eyepieces.
`In this case the long conjugate is on the right hand side
`of the lens, and the “front” ofthe eyepiece is the surface at the right hand ofthe diagram.
`This conforms to the usual way in which an eyepiece is shown in the layout of an optical
`system.
`
`The performance is indicated in approximate terms by the following graphs:
`
`(a) Spherical aberration, measured by the longitudinal aberration 65. When the spherical
`aberration is under-correct then as is negative;
`(b) Oflense against the Sine Condition, which indicates the presence or absence of coma
`in near central regions of the field;
`(C) Sagittal astigmatism, measured by the longitudinal aberration 65. When the sagittal
`focus lies closer to the lens than the paraxialfocalplane then as is negative;
`((1) Tangential astigmatism, measured by the longitudinal aberration 6t. The sign
`convention is the same as in (c);
`(e) The radial distortion, measured in per cent deviation of the radial distance of the
`image from the centre of the field. When the deviation is positive the actual image
`is at a greater distance from the centre of the field than the ideal image.
`
`All calculations are based on a nominalfocal length of 1.000 inches.
`For completeness the Petzval Sum is also given, as well as the back focus of the
`lens and its overall length.
`These values have been calculated at the Bell & HoWell Company. When no field
`or aperture values are specified in the patent literature the computers have been
`programmed to stop whenever the numerical value of 65 or at exceeds 0.015.
