METHOD OF MAKING CURVILINEAR REFLECTING SURFACE Russian patent published in 1996 - IPC

Abstract RU 2065616 C1

FIELD: lighting engineering. SUBSTANCE: flat bar is put onto array with its opposite reflecting surface. Then bar bent due to axial displacement of punch close to reflecting layer of bar. Load is rejected after process of forming of curvilinear form of optical surface is finished. Working surfaces of punch and array are made optical with cleanness and roughness being no worse than optical cleanness and roughness of corresponding reflecting surfaces of bar. After that bar is stretched by means of load into array. Before bending reflecting surfaces of bar should be treated with polyvinyl alcohol solution. EFFECT: improved precision. 1 tbl
