Description
[先行技術文献]
[特許文献]
但し、I0は入射光強度、δ=2πΔn・d/λである。
透過光強度が極小になるのは(3)式の条件が成立する場合である。
πΔn・d/λ=m (m=0、1,2、・・・)・・・・・(3)
(3)式の関係を用いると、透過率極小波長(λmin)の測定からΔndが求められる。本発明で使用した位相差板は波長550nm近辺において三次の極小(m=3)となるものを使用したので、(3)式は(4)式となる。
二枚の一軸性フィルムを用いた位相差板の合成位相差は、光軸を平行にして積層した場合は両者の和で、また光軸を直交して積層した場合は差で与えられる。ここで、位相差板のΔndをR、測定基板の方位角リタデーションをrとする。測定基板を位相差板の光軸と配向方向を平行にした場合の透過率極小波長をλp、位相差板の光軸と配向方向を直交させた場合の透過率極小波長をλTとすると、上記(4)式から次の(5)式、(6)式が得られる。
R−r=3λT ・・・・・(6)
(5)式から(6)式を引くことにより、(7)式が得られる。
つまり、分光光度計を用いてλpとλTを測定すれば、(7)式から測定基板の方位角リタデーションrが求められる。なおRとrは波長依存性を持つため(7)式は厳密には正しくない。しかし、微小位相差の測定ではλpとλTの値は接近しており(大きくても50nm程度)、位相差板に波長分散の小さいアートンフィルムを使用しているため、50nm程度の波長差での方位角リタデーションの波長依存はほぼ考慮する必要がなく、(7)式は適用可能である。
(3) 遠心分離機の中心軸と直交する方向にセルを固定し遠心分離(500rpm)を3分行い、さらに高圧エアーをセル内に吹き付けることでセル内の液晶を除去した。
