Pterygosomatidae_Pimeliaphilus_Arc183_ventr_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.<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的原始图像堆叠序列。
标本信息：该寄生螨幼虫包埋于一块不透明浅棕色化石树脂中，该树脂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。成像前采用临时甘油封片方式制备样品。
成像方法：使用尼康E-800、蔡司AxioImager A2及徕卡DM 2500正置显微镜完成成像。其中尼康显微镜配备40×、60×水浸物镜，蔡司与徕卡显微镜分别配备干式及油浸物镜；成像模式涵盖明场、偏振光及微分干涉差照明，并采用落射照明方式。通过搭配尼康显微镜的尼康D7000数码相机、搭配蔡司显微镜的蔡司Axiocam 506彩色相机及搭配徕卡显微镜的徕卡DFC450相机，采集包含多个焦平面的图像堆叠序列。后续使用Adobe Lightroom对图像堆叠进行色彩、亮度与噪声校正，最终导出为JPEG格式文件。
相关说明：显微镜型号、照明类型及放大倍数均记录于文件夹名称中。所有图像均附带比例尺。请注意：当文件名包含"x0.5"字样时，需将比例尺图像放大2倍后方可使用。
