| Popis: | Two original designs of mirror image rotator systems (IRS) on base of five plane mirrors with planar perpendiculars for panoramic plane pivots of the infrared solar spectrographs and circular review systems are considered. Comparison of conventional three-mirror IRS with proposed ones showed advantages of the latter, such as: mirror sizes' decreasings (in 1.8 - 2 times), decrease of the longitudinal and radial dimensions of the system (in 1.3 - 3 times) and optical pathlength for axis beam (in 1.25 - 3 times). |
