Abstract
Free-standing transmission gratings will be used in a new generation of space instruments for magnetosphere energetic neutral atom (ENA) imaging which requires efficient suppression of the exceptionally strong background extreme ultraviolet (EUV) and UV radiation. The first results of the experimental study of grating (period 200 nm) optical properties in the 50 - 130 nm wavelength range are presented. It is shown that grating transmission strongly depends on polarization of the incident radiation which makes gratings efficient polarizers. Possibilities of using a single grating and crossed gratings for EUV filtering are discussed.
