Abstract
Description
(N+1)/[(N*3/4+n*1/4)+n*(n*3/4+N*1/4)]
N=nとすると、比率は1/nであり、これは、本発明の第1の実施例が、ワイヤグリッドの消光比と同様のバックグラウンド抑制をもたらすことを示す。N<<nである場合、比率は約4/nである。ワイヤグリッドの典型的な消光比は、n=0.001である。
(N*3/4+1/4+n*3/4+N*n*1/4)/(N+n)
N=n及びn<<1(n=0.001の場合の一般的な値)の場合、比率は約1/(8*n)である。n<<1及びN<<n(すなわちワイヤグリッドより実質的に小さい消光比を有する偏光板53である)の場合、比率は約1/(4*n)である。
(3/4+N*1/4)+(N*N*3/4+N*1/4)/
(n*n*3/4+N*n*1/4)+(N*N*3/4+n*N*1/4)
N=nの場合、比率は3/(8*n*n)である。N<<nの場合、比率は約1/(n*n)である。
