The Student Research Laboratory for Optical Engineering was founded in 2014 at the Dept. of Applied and Computer Optics in ITMO University. Students there work on various optical, design, lighting and technological projects and find like-minded team for creating of coworking-groups in the student laboratory. It is highly difficult to provide practicaloriented activity in the laboratory without the use of elementary optical elements, which are supposed to be components of educational projects and activities. The review of traditional approaches for production of optical elements showed that currently there are no technologies in the optical industry, capable of solving this problem. The produced optical components must meet following requirements: a). to be capable to visualize optical elements work principles; b). to be produced rapid and laborless; c). to be affordable for students. This paper presents results of the experimental work, the technological process and the obtained elements characteristics, which were produced in two different ways. The optical elements angles were measured by goniometer and compared with preset tolerances.
Decreasing mass of telescope mirrors issue is still actual today. Common lightweighting mirrors method uses relief back structure. In the article it is proposed to change back flat surface to spherical one. Options of mirror design are considered: design of "negative" (with the smallest thickness in the center), "positive" (with the smallest thickness along the edge) meniscus and meniscus with the same thicknesses. The schemes of mounting such mirrors in telescope are considered.
Through the creation of a large number of interactive optical projects in pursuit of this goal, the laboratory has realized that the most effective educational approach is one that presents information in a fun, engaging, and informative manner. Hence, the idea for an optical labyrinth was born. This labyrinth allows students to interact with and learn optical phenomena in real time, presenting tangible benefits for ongoing education of optics and photonics in schools and universities.
In the article it is shown how lightweight a primary mirror of a space telescope can be made by using new material silicon carbide. The article includes theoretical calculations made with the help of software. The main aim of calculations is to get lightweight mirror with small optical surface deflections. The mirror diameter is more than 1 m.

In the article we studied the properties of silicon carbide by simulating them in program, the influens of it on deflections of mirror surface. Also the article shows what small changings in model are led to. We found some interesting results, which can help to the developers of mirrors.
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.
