U prvom dijelu diplomskog rada dan je povijesni pregled razvoja teleskopa. Opisani su pojedini nedostaci prvih teleskopa refraktora, kao i tadašnje teorije zbog kojih su kromatske aberacije dugo vremena bile misterija, što je odgađalo izum i razvoj reflektora. Središnji dio rada posvećen je zakonima geometrijske optike na kojima se temelji princip rada ne samo teleskopa, već i drugih optičkih instrumenata. Također, navedene su i opisane bitne karakteristike teleskopa. Upute kako samostalno izraditi jednostavan teleskop dane su u završnom dijelu rada u kojemu su dani i primjeri kako primijeniti teleskop u nastavi fizike u osnovnim školama i prirodoslovno-matematičkim gimnazijama.

The first part of this thesis includes the historical overview of the development of the telescopes. Certain disadvantages of first refractors are described, as well as theories for the cause and misunderstanding of chromatic aberration remained a mystery for a long time that delayed the invention and development of reflectors. The central part of the thesis deals with the underlying principle of the telescope and other optical instruments – laws of geometrical optics. Furthermore, the most important characteristics of telescope are listed and described in more detail later in the thesis. The final part of the thesis contains instructions that one can use in order to independently construct a simple telescope. Moreover, examples that are listed show how to apply the telescope in teaching physics in the primary and secondary schools.
