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 discussed.

摘要

针对制备在波长低至1000埃时具有最高反射率的氟化锂包覆铝镜展开了进一步研究。已制备出在波长λ = 1026埃时反射率为73%的镜子。在不同的镀膜制备条件下测量了蒸发氟化锂薄膜的消光系数k。描述了真空沉积具有最小k值的氟化锂薄膜以及具有最高反射率的铝 + 氟化锂镜的技术。讨论了在不同条件下氟化锂包覆铝镜的老化情况。
