詳細信息：富士NEUTRALDENSITY(ND)　Filters濃度補正濾色片簡稱減光片,應用于照相時在沒有辦法或不改變光源強度的情況之下,可以精確的調整曝光量.使得能夠在想要的光圈與快門速度條件下,拍攝特殊效果的景物.在LCD液晶顯示器產業,NDFilter常被用來減低面板亮度,以便在各種不同亮度的條件下檢查液晶表面波紋和亮點缺失,以及其它各種FPD的檢測應用.產品規格種類透光率%容許值(A光源)ND-0.179.4577.70-81.20ND-0.263.1060.02-66.00ND-0.350.2047.90-52.50ND-0.439.8538.00-41.70ND-0.531.7029.50-33.90ND-0.625.2023.50-26.90ND-0.720.0018.60-21.40ND-0.815.9014.80-17.00ND-0.912.6011.70-13.50ND-1.010.109.09-11.00ND-1.26.005.40-6.60ND-1.53.002.80-3.50ND-2.00.950.70-1.20A光源/色溫度=2854;C光源/色溫度K=6740應用組合透光率配合商品計算式:結果計1%ND-2.0Y=0.95%算2%ND-0.2ND-1.563.10%*3.00%=1.89%方3%ND-1.53.00%式4%ND-0.4ND-1.039.85%*10.10%=4.03%5%ND-0.3ND-1.050.20%*10.10%=5.07%6%ND-1.26.00%8%ND-0.1ND-1.079.45%*10.10%=8.02%10%ND-1.010.10%
