產品概覽

  • NG4、NG9 或 NG11 玻璃類型
  • 指定 0.15 至 5.0 的光學密度
  • 在可見光光譜產生均勻的光線衰減效果
  • 也供應 SCHOTT NG 灰色玻璃

SCHOTT NG 吸收型中性密度 (ND) 濾光片是由 NG4、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 0.15 至 5.0 的光學密度,協助簡化整合至光學系統。SCHOTT NG 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。5 至 160mm 的自訂尺寸及自訂光學密度,或是適合特定波長的穿透值,均可依要求供應;如需更多詳細資訊,請造訪本公司有色玻璃濾光片製造能力網頁。也供應 SCHOTT NG 灰色玻璃濾光片

每批濾光片都經過測量及調整厚度,以符合 546nm 的指定穿透值。濾光片批次效能不同可能導致標稱厚度變化;不過每批產品之間的穿透變化均維持在最低限度。

濾光片模擬軟體

請按此處下載 SCHOTT 有色玻璃濾光片計算程式,以用於計算每種 SCHOTT 玻璃類型的內部和外部穿透率。此程式可以根據使用者指定的厚度來模擬個別濾光片的效能,或模擬具有不同玻璃類型和厚度的堆疊式濾光片的效能。
