LP1600 Longpass Filter - 1550 nm Laser Blocking (Raman/Fluorescence)

LP1600 长通滤光片 - 1550 nm 激光阻挡（拉曼/荧光）

1550 nm 激光阻挡（拉曼/荧光）：

这1580 nm 波长处的 OD4 阻断这是关键规格。它足以阻挡来自标准的强信号。1550纳米激光器（常见于电信和激光雷达）同时允许检测波长大于 1620 nm 的斯托克斯位移拉曼散射或荧光信号。

LP1600 Longpass Filter - Semiconductor Inspection (Silicon Transparency)

LP1600 长通滤光片 - 半导体检测（硅透明度）

半导体检测（硅透明度）

硅在波长大于约 1100 nm 时变为透明。虽然 LP1100 是此应用的标准器件，但LP1600可用于专门的缺陷检测，或消除晶圆或锭块中特定亚表面特征的“较短”SWIR噪声（1100-1500纳米）。

产品常见问题

截止波长是指带通滤波器开始或停止透射光的过渡点；在实际系统中，它定义了允许通过的波长范围以及被削弱或阻挡的波长范围。

阻挡区是指滤光片设计用于抑制不需要的光线的波长范围；在实际系统中，更强或更宽的阻挡有助于减少背景信号、杂散光和探测器干扰。

阻挡深度/光密度 (OD) 描述了滤光片在阻挡区域对不需要光的抑制强度；例如，OD6 @ 200–1200nm 意味着滤光片设计用于阻挡 200–1200nm 波长的光，使其透射率降至约 0.0001%，有助于减少杂散光、背景信号和探测器过载。

入射角（AOI）是光线照射到滤光片表面的角度；随着AOI的增加，干涉滤光片可能会出现光谱偏移，通常会将透射或过渡波长移向更短的波长。
