Av. Mitrofanov et al., THE OPTICAL-PROPERTIES OF REGULAR MICROPOROUS MEMBRANES, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 405(2-3), 1998, pp. 319-322
Transmission coefficients in the spectral range of 115-350 nm were mea
sured for regular microporous polyethylene terephthalate (Lavsan) memb
ranes with a 1 mu m structure spacing. The obtained results are analyz
ed with account of diffraction phenomena and optical properties of the
membrane polymer. The optical properties of regular and normal track
membranes with commensurable pore sizes are compared. The investigated
samples can be used as diffraction filters for UV, EUV and VUV radiat
ion.
