Paper Abstract

Shape variable mirrors in a large telescope are suggested so that by using least mirrors and the simplest correctors excellent image quality will be acquired at all focal stations for various works. The topic of application of mechanical methods to the field of optical design and testing is put forward. 2. Based on the ideas of Rosin, Angel et al., we propose to use small correctors instead of big ones in cases when a continuous field is not necessary, e.g., multi-object spectroscopy. 3. Segmented field focal reducers and focal reducers of conical optical fibers are introduced. Segmented field correctors are also proposed. 4. An improved wobbling mode of the secondary mirror is introduced for in-frared observations. 5. The optical configuration of a 7.5-meter telescope with above new ideas is briefly described.
