In this paper, we consider ways to facilitate such as (radial-circular, triangular, hexagonal); holes; contour cross section of various shapes (single arch and double arch); sandwich, honeycomb structures. we examine the comparison of traditional and not traditional materials for large optics.
Student research laboratory for optical engineering is comfortable place for student's scientific and educational activity. The main ideas of laboratory, process of creation of laboratory and also activity of laboratory are described in this article. At ITMO University in 2013-2014 were formed a lot of research laboratories. SNLO is a student research (scientific) laboratory formed by the Department of Applied and computer optics of the University ITMO (Information Technologies of Mechanics and Optics). Activity of laboratory is career guidance of entrants and students in the field of optical engineering. Student research laboratory for optical engineering is a place where student can work in the interesting and entertaining scientific atmosphere.
This work devoted to a comparative study of different designs of lightweighted mirrors, as well as a comparison of materials, of which these mirrors are made of. We consider such methods of lightweighting as: pockets (radial-circular, triangular, hexagonal), holes, contoured back (single arch and double arch), so-called «sandwich» and selection of materials.
