Pterygosomatidae_Pimeliaphilus_Arc183_lat_60x_Leica_TumGU_p3

Original image stacks of the larval parasitic mite found in Early Cretaceous (Albian) Archingeay-Les Nouillers (= Font-de-Benon quarry) fossil resin locality.<br>Material - Inclusion in opaque, light-brown piece of fossil resin trimmed to an approximate parallelepiped 0.5x0.5x1.5 mm and polished on four sides. Housed in the amber collection of the Geological Institute and Museum of the University of Rennes, France, with collection number IGR.ARC.183. Photographed in temporary glycerol mounts.<br>Imaging: Compound microscopes Nikon E-800, Zeiss AxioImager A2 and Leica DM 2500 with water-immersion (Nikon, 40x and 60x), dry and oil-immersion (Leica, Zeiss) brightfield, polarized and differential interference contrast and incident illumination were used. Stacks of images, comprising multiple focal planes, were obtained with digital cameras Nikon D 7000 on Nikon microscope, Zeiss Axiocam 506 color on Zeiss microscope and Leica DFC 450 on Leica microscope. Stacks were corrected for colour, brightness and noise with Adobe Lightroom, then exported to .jpg.<br><br>Microscope, illumination type and magnification are recorded in the folder title. Scale bars are provided along with images. Note that scale bar image is to be scaled 2x when used with files containing x0.5 in the name.<br>

本数据集包含发现于早白垩世阿尔布期（Albian）Archingeay-Les Nouillers（即Font-de-Benon采石场）化石树脂产地的寄生螨幼虫原始图像堆栈。

标本详情：该标本为包裹于不透明浅棕色化石树脂中的内含物，树脂块被修整为近似平行六面体，尺寸约0.5×0.5×1.5 mm，并对四个侧面进行了抛光处理。标本馆藏于法国雷恩大学地质研究所与博物馆的琥珀馆藏中，馆藏编号为IGR.ARC.183。拍摄采用临时甘油封片方式。

成像流程：使用尼康（Nikon）E-800、蔡司（Zeiss）AxioImager A2及徕卡（Leica）DM 2500复合显微镜完成成像。其中尼康显微镜配备40×、60×水浸式物镜，蔡司与徕卡显微镜则配备明场、偏光、微分干涉相差及落射照明系统，支持干式与油浸式物镜。通过配套数码相机采集多焦平面图像堆栈：尼康显微镜搭载尼康D7000数码相机，蔡司显微镜搭载蔡司Axiocam 506 color数码相机，徕卡显微镜搭载徕卡DFC450数码相机。所得图像堆栈经Adobe Lightroom完成色彩、亮度与噪声校正后，导出为JPEG格式文件。

文件夹命名中记录了所用显微镜、照明类型及放大倍率信息。所有图像均附带比例尺。需注意：当使用文件名包含“x0.5”的图像文件时，需将比例尺图像放大2倍后使用。
