This paper describes the work of modifying the Sartorius iris photometer at the Purple Mountain Observatory. By using an oscilloscope with high gain amplifier instead of the simple tuning indicator tube, the balance error may be reduced to about 1/7—1/10 of that of the original apparatus. At the same time, the supply of the photoelectric-multiplier is replaced by a highly stable electronic voltage stabilizer in order to improve the stability of the instrument further. After measuring and comparing the zero-point drift under various conditions, it is shown that the dependence of drift on humidity seems to be more important than that on temperature. Besides, the dark current of photoelectric-multiplier and the size of iris will also have influence on the drift. With the box of photoelectric-multiplier hermetically sealed in a dry circumstance, the drift is apparently reduced to less than a half division per hour in the stable state. With the help of the relation between iris area and reading, measured by the authors, the balance error is discussed. The result we obtained does not agree with Argue's. In our case, the smaller the iris, the smaller would be the balance error. Finally, the results of measuring 36 stars in the open cluster IC4665 with the improved and the original apparatus are shown in Fig. 7.

本文描述紫金山天文台的萨尔托累型光瞳光度计(Sartorius Iris Photometer)的改装工作。用了一具带高增益放大器的示波器代替简单的调谐指示管,使平衡誤差减小,较原装置改善约7—10倍。同时,光电倍增管的供电换用一高稳定的电子稳压器,使仪器的稳定性得以改善。经过测量和比较看出湿度对漂移的影响比溫度大。此外,光电倍增管的暗流和光瞳大小也影响着漂移。还讨论了平衡誤差,得出光瞳读数取得越小,则平衡誤差也越小。最后,给出分別用改装后和原来的装置测量疏散星团IC4665中36颗星的结果。
