Photomicrographs of thin sections provide a swift and efficient means of sharing information for consultation, education, documentation and publication within the Geosciences and related areas. In general terms, the main way to capture digital microscopic images involves the use of a mounted camera unit on a high-end costly benchtop microscope. However, freehand methods to capture microscope-scale images using a smartphone, as well as smartphone adapters that can be attached to a microscope have emerged during recent years. This paper presents the design features of a costless system able to obtain photomicrographs without requiring a conventional microscope. The imaging device is comprised of a mini-objective lens attached to a smartphone and a structure that allows it to focus as well as to rotate the stage and to insert/remove a polarized sheet. The quality and magnification of the images attainable from the new design is comparable to the images normally obtained by a conventional petrographic microscope using a ×4 objective and a ×10 ocular (total magnification ×40).
薄片的显微照片为地球科学及相关领域内的咨询、教育、记录和出版提供了一种快速而高效的信息共享方式。一般来说，获取数字显微镜图像的主要方法涉及在高端昂贵的台式显微镜上使用安装的相机单元。然而，近年来已经出现了使用智能手机进行显微镜级图像的徒手捕捉方法，以及可以连接到显微镜上的智能手机适配器。本文介绍了一种无需传统显微镜即可获取显微照片的无成本系统的设计特点。成像设备由附接到智能手机的微型物镜和一个结构组成，该结构允许其聚焦以及旋转载物台并插入/移除偏光片。从新设计中获得的图像的质量和放大倍数与使用 ×4 物镜和 ×10 目镜（总放大倍数 ×40）的常规岩相显微镜获得的图像相当。
