產品系列說明

  • 視訊校準
  • 永久的密度標準
  • 評估/比較相機的動態範圍

非常適用於視訊或光學檢測系統及相機的評估。便利的尺寸 (標稱值為50.8 x 50.8 x 1.5mm) 可供直接檢視,也可使用35mm測試片投影機進行投射。圖案是「標準」,包含兩項刻度:EIA等步長透射率 (線性) 與EIA等步長密度 (對數)。每項刻度有九個步長,穿透率範圍從3%至60% (EIA 20:1)。所有步長都由超精密的半色調圖案準確提供。節距為0.001”。步長採用並列的0.200”x 0.100”,無空白或邊界。穿透率與密度如下所示 (具有嚴格的容差)。刻度採用永久的鉻膜玻璃材料製成,可承受惡劣的環境。背景不透明,其光學密度為3.0 (透射率 = 0.1%)。
