CHROMOSPHERE TELESCOPE Russian patent published in 1999 - IPC

FIELD: optical instrumentation, astronomical instruments. SUBSTANCE: invention can find use in telescopes intended for observation of chromosphere of the Sun within wide region of spectrum. Proposed chromosphere telescope includes mirror objective lens-paraboloid, field lens, interference-polarized filter installed at angle with regard to optical axis of telescope so that its optical axis matches central reflected beam, mirror-projection objective lens that tunes image of chromosphere to photodetector. Focal distance of field lens equals distance to entrance pupil of objective lens. EFFECT: provision for telecentric path of beam on interference-polarized filter, uniform spectral composition of image. 1 dwg
