Paper Abstract

The transmission of thin indium filters was measured in the EUV wavelength range between 500 and 1200 angstroms. Our results for the shape of the transmission peak are consistent with previous measurements, indicating a FWHM bandpass between 750 and 900 angstrom with the maximum at 770 angstrom. The absolute transmission values however differ significantly from former measurements. The results are compared to currently used predictions. The filter transmission was remeasured after 20 months storage in N2. On average, the transmission was observed to be reduced to about 60% of the original value.
