Abstract
We have been developing ultrathin multilayered plastic foils for use as radiation entrance windows in satellite borne position sensitive proportional counters (PSPC) for imaging ultrasoft X-rays from celestial sources. The access windows are supported by two mechanical grid systems. The techniques to prepare and manufacture the access windows will be described. Results of measurements of individual windows as well as imaging performances of PSPC's equipped with specified windows will be given.
