Calculation of coefficients of cassegrain telescope mirrors

الملخص EN

In the present work, a program for calculating the coefficients of the Aplanatic Cass grain Telescope (ACT) system, free from the effects of spherical and coma aberrations were constructed.

In addition, the two-mirrors of the optical system, as spherical surfaces, were adopted.

This means, that the two-equations of the mirrors are assumed to be polynomial function of five even terms only.

The numerical method, least-squares curve fitting method to calculate the two-mirror coefficients system, was adopted.

For choosing the values and ratios that give the best results, Rayleigh Criterion (Rayleigh Limit), for purpose of comparison and preference, was adopted.
