圆形连续ND滤波器

BK7 安装式 B270 Quartz 涂层图表联系下单！

BK7 在一般可见光和近红外波长中具有出色的透射率，因此使其成为用于 Neautral 密度滤光片的理想选择。BK7 圆形连续 ND 滤光片可以通过沿其中心轴旋转来调整要传输的入射光束的强度。通过的光谱将继续保持其中性光谱能量分布。该滤光片通常用于激光和医疗应用。通过组合两个滤波器，可以在更大区域内获得固定密度衰减效果。我们滤光片的光谱范围为250-2500nm。

衰减水平由滤光片的光密度（OD）指定。

OD 定义为传输系数以 10 为底的对数为负数，

该方程式可以表示为：

OD= - Log₁₀ （T/100），

其中 T 是以百分比表示的传输。

例如，T= 1% 的中性密度滤光片的 OD 为 2。
