Earth AtmosphereSolar-Occultation Imager Optics Cathy Marx [Dennis Evans] 2 August 2002
General System Description • Main Pupil • Radius = 4400 mm • should be increased to 4425 to illuminate outer 25 mm • need to rescale Px dimensions • Individual Telescopes • Afocal, dual paraboloid • Primary • Aperture = 425 mm radius • Vertex Radius = -2631.578947 mm • Secondary • Aperture = 24 mm radius (to 30 to shadow Fold 1) • Vertex Radius = -131.578947 mm • Intervertex Distance • 1250 mm
Status • Delay Lines • Being located so they don’t exceed boom length • Being located on opposite sides of centerline to avoid interference • This may increase the size of the combiner significantly • Collector Spacing • Even dimension spacing causes excess flux in “wings” of PSF interferogram • ZEMAX Tech Support • PLEN (Path Length) misses surface problem in Merit Function Editor
X-fan Layout; Telescope 1 at X= -0 mmCombiner is at X= 1000 mm
