The OPARA service was recently upgraded to a new technical platform. You are visiting the outdated OPARA website. Please use https://opara.zih.tu-dresden.de/ for new data submissions. Previously stored data will be migrated in near future and then the old version of OPARA will finally be shut down. Existing DOIs for data publications remain valid.

Research objectsTissue: thin sections of teeth with carious lesions
AbstractThis dataset contains the images of 24 selected thin sections examined with polarized light microscopy. The thin sections were examined with a Leica DMRB polarizing microscope (Leica Microsystems GmbH, Wetzlar, Germany) using a magnification of 2.5 times. The photographs during examination were acquired with a digital camera (sony α7, Sony, Tokyo, Japan) using the following settings: exposure time of 1/160 s, ISO sensitivity of 125. Three photographs are available for each thin section. The first photograph shows the examination using conventional polarized light microscopy with the polarizer and analyzer rotated at 90° to each other (cross-polarized PLM, or PLMc). The second photograph displays the thin section using polarized light microscopy as in PLMc with an additional λ-plate prior to the analyzer (red-plate PLM, or PLMr). The third photograph shows the examination with transmission light microscopy without the analyzer being used (bright-field microscopy, or PLMb). The order of the images in the folders is always the same: PLMc, PLMr, PLMb, where for each photo always a processed .JPG file and the raw data as acquired .ARW file is available. The pixel size in each image is 2.28 µm x 2.28 µm.
