It aimed to clarify what feature the shape of the coccolith had in optics, UV-VIS-IR spectrum of calcite single crystal were measured. In the absorption of the infrared region, there is remarkable anisotropy by the crystallographic orientation. The anisotropy can be treated as a rotational symmetry around c axis. The result of supporting it was obtained even for the measurement that used coccolith of nature.

为了阐明颗石的光学形状特征，对方解石单晶进行了紫外-可见-红外光谱测定。在红外区的吸收中，晶体学取向导致了显著的各向异性。各向异性可以被视为绕c轴的旋转对称。甚至对于使用自然界颗石的测量也获得了支持它的结果。
