(a) Transmission of a 300 nm-thick silicon nitride film at angles ranging from 0.18° to 0.26°. (b) Transmission of a second 300 nm-thick silicon nitride film at angles 0.22° and 0.24°. The small peaks between 8 and 9 keV in the transmission curves are a result of both copper and zinc fluorescent contamination in the signal that we were unable to eliminate, which most likely originated as trace elements within the Kapton tape. |
