For light microscopy, small organisms and their determination-relevant organs and structures are frequently mounted in water soluble media (e. g. glycerine jelly, chloralhydrate- and gum arabic-based mounting media, polyvinyllactophenole). The advantage of these media is that a preceding dehydration of the objects is not necessary and that the organisms generally maintain their natural body shape. An important disadvantage of these media is the limited durability of the slide mounts prepared with them.For collections (incl. type material) this can be problematic, since re-mounting might in some cases damage the object and is often not realizable due to the high time requirement involved.An almost complete photographic documentation of such objects will contribute to a permanent preservation of most of the object information. The resulting photos can be made publically available via the internet making loans obsolete und thus minimizing the danger of losing valuable collection material.The project aims at developing standards for the most possibly complete light microscopic documentation of slide mounts. Thereby a broad range of light microscopic methods (e. g. phase contrast, differential interference contrast, confocal microscopy) will be tested in order to determine the optimal combination of methods for the respective group of objects and organisms. Since most objects are three-dimensional, a photographic record in the form of focus stacks is intended. Via the database SeSam the photos will be made availabe via an internet platform for a large community of users. In order to improve the internet searchability of digital images of this object class, a broad discussion of their metadata concurrent with the production of photo sets will be initiated.Located at the Senckenberg Museum of Natural History Görlitz a diverse and important collection(including type material for approx. 400 species) of important taxa of soil mesofauna (Nematoda, Tardigrada, Acari, Plathelminthes, Collembola, Protura) exists, which is curated by a permanent staff of specialists. Many objects of this collection are slide mounts. The concentration of relevant material and the necessary expertise in Görlitz creates an ideal situation to develop and improve the standardization of digitizing microscopic three-dimensional objects. Starting from this core, the project aims will be published and cooperations with other institutes solicited in order to include similarly preserved objects (e. g. from other zoological and botanical collections).

对于光学显微镜，小生物体及其测定相关的器官和结构通常安装在水溶性介质中（例如，G.甘油凝胶、基于水合氯醛和阿拉伯树胶的封固剂、聚乙烯基乳酚）。这些介质的优点是不需要预先对物体进行脱水，并且生物体通常保持其自然体形。这些介质的一个重要缺点是与它们一起准备的幻灯片支架的耐久性有限。这可能是有问题的，因为重新安装在某些情况下可能会损坏对象，而且往往是无法实现的，由于涉及的时间很长。一个几乎完整的照片文件，这类对象将有助于永久保存大多数对象的信息。由此产生的照片可以通过互联网提供，使贷款过时，从而最大限度地减少丢失有价值的收藏材料的危险。该项目旨在制定最可能完整的载玻片架光学显微镜文件的标准。因此，广泛的光学显微镜方法（e。G.相位差、微分干涉差、共焦显微镜）进行测试，以确定用于相应对象和生物体组的方法的最佳组合。由于大多数物体都是三维的，因此打算以焦点堆栈的形式进行摄影记录。通过数据库SeSam，这些照片将通过互联网平台提供给广大用户。为了提高这一实物类别的数字图像在互联网上的可搜索性，将在制作照片集的同时对其元数据进行广泛的讨论。位于森肯贝格自然历史博物馆的Görlitz有一个多样化和重要的收藏（包括大约100万美元的类型材料）。400种）的重要分类群的土壤中型动物（线虫，缓步动物，阿卡里，板蠕虫，弹尾目，原尾目）存在，这是由一个常设工作人员的专家策划。此收藏中的许多对象都是幻灯片底座。相关材料的集中和必要的专业知识在Görlitz创造了一个理想的情况，以发展和提高数字化微观三维物体的标准化。从这一核心出发，将公布项目目标，并征求与其他机构的合作，以便纳入类似的保存对象（例如，G.其他动物学和植物学收藏）。
