Abstract
Inventia se refera la un procedeu de realizare a unui triplet cu alaun de potasiu, utilizat, în special, în constructia aparatelor optice. Procedeul este caracterizat prin aceea ca o lentila biconvexa si o lentila menisc sînt executate la forma si dimensiunile finale, urmînd prelucrarea unei fete de lipire pe o lentila biconcava din alaun de potasiu, cercetarea li lipirea acesteia la rece într-un dublet, în ansamblul dubletului prelucrîndu-se o a doua fata, dupa care aceasta se lipeste centrat cu lentila biconvexa.The invention relates to a process for making a potassium alum triplet, used in particular in the construction of optical devices. The process is characterized by the fact that a biconvex lens and a menisc lens are executed in the final shape and dimensions, following the processing of a gluing face on a biconcave of potassium alumina, the research of which is cold bonding in a doublet, in the doublet a second face is processed, and then it binds centered on the biconvex lens.
