国际皮埃尔·俄歇合作组织已开始在其位于阿根廷门多萨省的南半球实验场地调试一个工程阵列。它包含了两个原型的余辉望远镜，在山上的一座新建筑物内，俯瞰粒子探测器地面阵列的第一部分。这些望远镜的设计遵循施密特布局，具有大球面镜和用于减少慧形像差的光阑系统。大约0.5度的光学分辨率由球面像差支配。由铝合金板加工的金刚石铣削镜段被开发出来，并与玻璃镜元件一起用于原型中。这些铝镜非常坚固，具有良好的光学质量。为了增加望远镜的信号/噪声，在光阑中实现环形施密特校正透镜。校正环将望远镜的有效接收能力提高了约100倍，校正环由具有高紫外线透射率的特殊PMMA制成。详细介绍了反射镜和透镜的生产。将讨论元件的光学测试和特性。联系人：H。O.

The international Pierre Auger collaboration has started the commissioning of an engineering array on its southern hemisphere experiment site in the province of Mendoza, Argentina. It contains two prototype uorescence telescopes in-side a new building on a hill overlooking the first part of the ground array of particle detectors. These telescopes are designed following a Schmidt layout with large spherical mirrors and a diaphragm system for the reduction of coma aberration. The optical resolution of about 0.5 degree is dominated by spherical aberration. Diamond milled mirror segments machined from aluminium alloy sheets were developed and are used in the prototypes together with glass mirror elements. These aluminium mirrors are very robust and of good optical qual-ity. To increase the signal/noise of the telescopes an annular shaped Schmidt corrector lens is implemented in the diaphragm. The ring enlarges the effective acceptance of the telescopes by about 100corrector ring are made from special PMMA with high UV transmittance. Details of the mirror and lens production are presented. Optical tests and properties of the elements will be discussed. Correspondence to: H. O. Klages (klages@bk.fzk.de)
