市售显微鏡摄影机价格昂貴,且不易获得,較难广泛使用。我們曾試用一錐形小木箱代替摄影机来拍摄标本,获得滿意效果。一、用具及构造: (1) 暗箱:用三合板制成一錐形睛箱,底边为20×18公分,高12公分。里面涂以黑色。錐端制一圓孔,这一圓孔需与鏡筒紧密相接,不可透入光綫。 (2) 滴定架和固定夹:作为固定錐形暗箱及調节其距离用。 (3) 普通显微鏡一架:置于暗箱下面,与錐端圓孔紧套在一起。
Microscopes on the market are expensive and difficult to obtain, making it harder to use widely. We have tried a cone-shaped wooden box to replace the camera to take specimens, get satisfactory results. First, the appliances and structures: (1) dark box: made of a cone with a triangular box, the bottom of 20 × 18 cm, 12 cm high. Painted black inside. Tapered end of a round hole, the hole must be closely connected with the lens barrel, not penetrating the light. (2) titration rack and retaining clip: as a fixed cone dark box and adjust the distance. (3) an ordinary microscope: placed in the dark box below, with the cone-shaped round hole tightly together.
