Software for Optical Design and Analysis

Ken's Telescope On-line Calculator. This telescope calculator takes the objective diameter, f ratio, focal length, eyepiece apparent field, and eyepiece focal length as required to calculate the estimated objective performance, telescope magnification, magnification per inch, true field, and exit pupil size. It is a great way to compare the characteristics of different eyepieces. The calculator requires a JavaScript compatible browser. [Detail>>>]

Peter Enzerink' Telescope and Eyepiece On-line Calculator. There are two calculators here, one for a telescopes, and another for eyepieces in that telescope. Calculations are all cross linked, so changes that logically effect other calculations causes all relevant figures to be updated. This works between the telescope and eyepiece calculators.

Achromat: a two-element lens which brings two colors to a common focus. [Detail>>>]

Aplanatic: a lens that minimizes spherical aberration and eliminates coma. This can be done with a single lens if the front and back surface power are in the ratio of F1 = 6F2. It can be done with two or more lenses with more flexibility.

Apochromatic: formally, a lens design that brings three wavelengths to a common focus. [Detail>>>]

Astigmatism: canonically, astigmatism exists when there is a difference between the optical power of the optical system in the tangential plane and that in the sagittal plane. [Detail>>>]

Ronchi Test: In this centennial of Vasco Ronchi's birth it seemed appropriate to devote one of these columns to the well-known method of testing optical systems that he developed in the 1920's. [Detail>>>]
