Abstract

An Australian ruling engine has been operating at the Division of Chemical Physics, CSIRO, Melbourne, since January 1960, construction having commenced in March 1958. The engine, which has a capacity of 14 cm x 18 cm, has now ruled approximately 250 gratings which show efficiencies of 60-80%, Rowland ghost intensities of approximately 0.01% of the parent line (638/mm,first order), and first order wavefronts within one-fifth of a fringe, over a ruled width of 15 cm. Ruling speed is 19 grooves/min. No servomechanism or period corrector is used.

摘要

自1960年1月起，一台澳大利亚刻划机一直在墨尔本联邦科学与工业研究组织（CSIRO）的化学物理分部运行，其建造工作于1958年3月开始。这台刻划机的尺寸为14厘米×18厘米，现已刻划了大约250块光栅，这些光栅的效率为60%-80%，罗兰鬼线强度约为母谱线（638线/毫米，一阶）的0.01%，在15厘米的刻划宽度上，一阶波前误差在五分之一条纹以内。刻划速度为每分钟19条线槽。未使用任何伺服机构或周期校正器。
