optical instrumentation, recording of high-quality image of chromosphere of full sun's disk in wide region of spectrum. SUBSTANCE: chromospheric telescope includes reflecting objective- paraboloid, lens of field, interference-polarization filter set at angle to optical axis of telescope so that its optical axis matches central reflected ray, reflecting projection lens turned through certain angle with reference to optical axis of telescope and photodetector. Focal distance of lens of field equals distance to entrance pupil of objective securing telecentric path of rays to interference-polarization filter and homogeneous spectral composition of image as result of it. EFFECT: reduced dimension of telescope. 1 dwg
