  • 專為特定波長校正
  • 指定 0.3 至 3.0 的光學密度
  • NG3, NG4, NG5, NG9, 或 NG11 玻璃類型

SCHOTT 吸收型中性密度 (ND) 濾光片經過測試及校正,在405nm、633nm 或 785nm 波長可達到精確的光密度公差。是由 NG3, NG4, NG5, NG9 或 NG11 SCHOTT 玻璃類型組成,可於可見光光譜透過吸收產生均勻的光線衰減效果。這類濾光片製造時指定 0.3 至 3.0 的光學密度,協助簡化整合至光學系統。SCHOTTNG 吸收型中性密度 (ND) 濾光片供應 50 x 50 mm 的標準尺寸,並可堆疊多個濾光片以達到自訂光學密度。每個濾光片都含有引用測量值的校正證書。

請注意: 若需客製 SCHOTT 校準中性密度濾光片的尺寸,請聯繫我們。
