Research on rectangular-wave broadband pass filter film

  • 摘要: 对矩形波宽带通滤光片进行了深入研究,提出了一种设计、制备矩形波宽带通滤光片的方法。使用该方法设计并制备了400 nm~1100 nm波段,中心波长λ0=515 nm,透射带λ=λ0±25 nm,透射带平均透射率$\bar \tau $≥92%,截止带λ=400 nm~475 nm、λ=555 nm~1 100 nm,截止带透射率小于0.1%的矩形波宽带通OD3-A滤光片。对样片光谱进行了测试,结果满足需求。该方法设计、制备矩形波宽带通滤光片克服了F-P型窄带滤光膜监控精度要求高、通带宽带窄、成本高以及传统长、短波截止膜组合方式膜层总厚度过大、通带透过率低、波形矩形度差的缺点。
