用于单色光 (220, 254, 275 nm) 检测
配有带通滤波器的硅光电二极管 S12742 系列
S12742 系列的窗口使用干涉滤波器，仅对单色光敏感。
此系列包含三种具有不同中心灵敏度波长的类型：220 nm、254 nm 和 275 nm。
光谱灵敏度特性半宽度 (FWHM) 在 10 nm（典型）处极窄，因此可以准确进行光度测量，同时杂散光极少。
S12742 系列可定制，以支持其他最大灵敏度波长，例如 340 nm、560 nm。
它可用于水质分析、大气分析和汞灯的紫外线监测。

2 W 氙气闪光灯模块 L13651 系列
L13651 系列是一个集成了电源和触发开关的 2 W 氙气灯模块。
这些光源模块是世界上功率等级最小的模块，具有高度的空间设计自由度。
它们可以使用 5 V 电池，因此适合组装到便携式分析仪器中。其他特点包括高稳定性和长寿命。
此外，当这些光源模块与硅光电二极管 S12742 系列结合使用时，每次闪光的高发光效率有助于实现高精度分析和测试。
