Hughes Danbuiy Optical Systems successfully manufactured three sets ofcomplex sample cells for the Space Shuttle PHaSE (and planned PCS) experiment. Each sample cell assembly consists of an F/.55 spherical lens and an F/.45 parabolic skirt (with 3000 ? of full aperture aspheric departure and 60 2 of departure over the annular clear aperture). Each is manufactured to exacting fabrication, metrology, coating and assembly tolerances.
