Dr. Petra Haas studied Biology at the University of Heidelberg and the University of Massachusetts. In 2003, she moved to the Max-Planck Institute for Developmental Biology in Tübingen to study collective migration in the Zebrafish lateral line. She finished her PhD in 2007 at EMBL in Heidelberg and continued working on fish development, now using Medaka as a model organism. After one year as Technical Support Specialist at Thermo Fisher Scientific, she joined Leica Microsystems in 2012 as Product Manager for Confocal Software and the Digital LightSheet (DLS).

使用安装框架进行光片样品准备

样品处理通常是光片显微镜研究中的一个关键话题。徕卡显微系统的TCS SP8 DLS将光片技术集成到倒置共聚焦平台中，因此可以利用关于样品安装和XY-stage功能的一般原则。本文将描述一组安装框架，这些框架不仅允许准备更多的样品，尤其是在使用诸如BABB（苯甲醇苯甲酸酯）等潜在有害的安装介质时，亦具有广泛的适用性。

使用旋转设备进行光片样本安装

TCS SP8 DLS 显微镜采用了一种创新的设计理念，将光片显微技术集成到共聚焦显微镜中。得益于其独特的光学架构，样本可以像进行标准共聚焦成像一样，安装在标准玻璃底培养皿上。与传统的样本安装程序相比，这一过程只需进行少量调整。

使用 U 形玻璃毛细管进行样品装载

徕卡显微系统的DLS显微镜系统是一种创新概念，将光片显微技术集成到共聚焦平台中。由于其独特的光学结构，样本可以安装在标准玻璃底培养皿上，与传统的安装程序相比，几乎不需要或只需很少的适应。在这里，我们介绍了一种便捷的方法，能够快速准备样本以进行光片成像。

共聚焦成像和光片成像

光学成像仪器可以放大微小物体，聚焦遥远星体，揭示肉眼看不见的细节。但是，它有一个众所周知且令人烦恼的问题：景深有限。我们的眼睛（也是一种光学成像装置）也有同样的困扰，但我们的大脑在信号到达意识认知之前会巧妙地移除所有不在焦点上的信息。
