Further Studies on LiF-Overcoated Aluminum Mirrors with Highest Reflectance in the Vacuum Ultraviolet

Abstract: Further studies have been made on the preparation of LiF-overcoated aluminum mirrors with highest reflectance at wavelengths down to 1000 A. Mirrors with 73% reflectance at lambda = 1026 A have been made. The extinction coefficient k of evaporated LiF films has been measured under various conditions of film preparation. Techniques for vacuum depositing LiF films with the smallest K and Al + LiF mirrors with the highest reflectance are described. Aging of LiF-coated Al mirrors under various conditions is discus… Show more

“…Similar results have also been obtained by quantum molecular dynamics (QMD) simulations based on DFT [29]. In addition, the peaks at 11.6 The experimental data of pure LiF crystal was obtained by [30] and [31]. [32] have investigated the reflectance between 1 and 30 eV, which is used to compare the calculated reflectance spectra.…”

“…5 shows the refractive index of the pure LiF and the O-doped LiF crystal in theoretical and experimental conditions. The experimental data in the range of 0 − 14 eV is available by Cox and Johannsen [30,31]. The refractive index from the calculated pure LiF crystal supports experimental results at a low energy range.…”

“…Recubrimientos que operan por reflexión: en la actualidad no existen recubrimientos capaces de seleccionar una banda estrecha. En cambio sí se dispone de espejos eficientes de banda ancha, que están basados en la elevada reflectancia del Al y la transmitancia de una lámina protectora de LiF [28] [29] [30], el material de la naturaleza que tiene el cut-off (borde de absorción, longitud de onda por encima de la cual el material es transparente) en la longitud de onda más corta posible: 105 nm;…”

“…Por el contrario, en el intervalo espectral entre 100 y 115 nm, y en particular, en la línea Lyman β, no existen en la actualidad recubrimientos eficientes de banda estrecha, aunque son bien conocidos los espejos de banda ancha basados en Al recubierto con LiF, los cuales presentan una alta reflectancia desde una longitud de onda tan corta como la línea Lyman β [28] [29] [30].…”
