Pterygosomatidae_Pimeliaphilus_Arc183_lat_60x_Leica_TumGU_p4

Original image stacks of the larval parasitic mite found in Early Cretaceous (Albian) Archingeay-Les Nouillers (= Font-de-Benon quarry) fossil resin locality.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.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.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.本数据集包含采自早白垩世（阿尔布期）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。 样本信息：该寄生螨为包裹于不透明浅棕色化石树脂中的内含物，树脂块被切割为近似平行六面体（尺寸约0.5×0.5×1.5 mm），并对四个侧面进行了抛光处理。该标本馆藏于法国雷恩大学地质研究所与博物馆的琥珀藏品库中，藏品编号为IGR.ARC.183。成像前采用临时甘油封片法制备样品。 成像流程：使用尼康E-800、蔡司AxioImager A2及徕卡DM 2500正置复合显微镜开展成像工作，具体配置如下：尼康显微镜搭配水浸物镜（40×、60×）；徕卡、蔡司显微镜支持干镜与油镜成像，采用明场、偏光及微分干涉差照明，同时配备落射照明功能。通过配套数码相机采集多焦平面图像堆栈：尼康显微镜搭配尼康D 7000相机，蔡司显微镜搭配蔡司Axiocam 506彩色相机，徕卡显微镜搭配徕卡DFC 450相机。所有图像堆栈均通过Adobe Lightroom软件进行色彩、亮度与噪声校正，随后导出为JPEG格式文件。显微镜型号、照明类型及放大倍数信息均记录于文件夹命名中。所有图像均附带比例尺标尺；需注意：当文件名包含"x0.5"字样时，配套的比例尺标尺需放大2倍后方可使用。
