Pterygosomatidae_Pimeliaphilus_Arc183_dors_Nikon_x20x0.5_BF&incident

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>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。<br>标本详情：该寄生螨幼虫包裹于一块不透明浅棕色的化石树脂（琥珀）中，标本被切割修整为近似平行六面体的块体，尺寸约为0.5×0.5×1.5 mm，其四侧均经抛光处理。标本现馆藏于法国雷恩大学地质研究所与博物馆的琥珀标本库，馆藏编号为IGR.ARC.183。成像前采用临时甘油封片法制片。<br>成像参数：实验使用尼康（Nikon）E-800、蔡司（Zeiss）AxioImager A2及徕卡（Leica）DM 2500复式显微镜（Compound microscope），其中尼康显微镜配套40×、60×水浸物镜，蔡司、徕卡显微镜配套干镜与油浸物镜；照明方式涵盖明场、偏振光、微分干涉差及落射照明。通过各显微镜配套的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数码相机，蔡司显微镜搭配蔡司Axiocam 506彩色数码相机，徕卡显微镜搭配徕卡DFC 450数码相机。所有图像堆栈均经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。<br><br>所用显微镜型号、照明类型及放大倍数均已记录在文件夹名称中。所有图像均附带比例尺。请注意：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倍后方可使用。
