组织切片染色标本的显微摄影已有较完善的成套方法.然而,在这类光镜或电镜所摄影记录的倍数均在40倍至1000倍,甚至几十万倍(电镜)以上,它们都具有一个共同的特点,即视野范围随放大倍数增大而缩小(倍数与视野范围之间呈反比例关系),即使在放大倍数最低的现代体视显微镜上,由于光学机械特性限制,要获得10倍率的最大视野范围实际上也仅在0.3毫米左 Tissue sectioned stained specimens have been well-established in photomicrography, however, the magnifications recorded in such light or electron microscopy ranged from 40 times to 1000 times, or even hundreds of thousands times (electron microscopy), and both Has the common feature that the field of view narrows as the magnification increases (multiples of the field of view is inversely proportional to), even in the lowest magnification of the modern stereo microscope, due to the limitations of the optical mechanical, to obtain 10 times the rate The maximum field of view is actually only 0.3 mm left
