此 BP690-20 带通滤光片旨在传输 690 nm 附近窄的红色波段,同时减少不必要的带外光。
它适用于使用红色 LED 照明或以 690 nm 为中心的信号检测的机器视觉、荧光成像和光学传感系统。它有助于隔离目标红色信号,强烈减少通带外的背景干扰,并保留可用信号亮度以进行更高对比度的测量。
主要规格:
- 波长/主要规格:690 nm 中心波长 (CWL)
- 带宽/过渡规格:20 nm 半高宽 (FWHM)
- 透射率/阻挡:透射率 > 90%;200–1100 nm 范围内 OD6 阻挡
- 尺寸/可用性:提供 12.5 mm 至 34 mm 直径以及 M25.5×0.5 至 M55×0.75 螺纹安装座
