Confocal data of Clessidromma palmeri, holotype, NIGP166270

This dataset contains the raw confocal laser scanning microscopy (CLSM) slices for the holotype of <em>Clessidromma palmeri</em> (NIGP166270) from mid-Cretaceous Burmese amber. This dataset is associated with the publication "Revisiting the morphology of the Cretaceous ommatid beetle <em>Clessidromma palmeri</em> (Coleoptera: Archostemata: Ommatidae)" (DOI:10.11606/1807-0205/2021.61.95). Confocal images were obtained with a Zeiss LSM710 confocal laser scanning microscope, using 488 nm Argon laser excitation line. Both original CZI files and exported TIFF stacks are provided.本数据集包含产自白垩纪中期缅甸琥珀的克莱氏眼甲（*Clessidromma palmeri*）正模标本（标本编号NIGP166270）的原始共聚焦激光扫描显微镜（confocal laser scanning microscopy, CLSM）切片图像。本数据集关联学术论文《重议白垩纪眼甲科昆虫克莱氏眼甲（鞘翅目：原鞘亚目：眼甲科）的形态学特征》（DOI:10.11606/1807-0205/2021.61.95）。该共聚焦图像通过蔡司LSM710共聚焦激光扫描显微镜采集，采用488纳米氩离子激光激发光路。数据集同时提供原始CZI格式文件与导出的TIFF图像堆栈。
