Độ dốc cạnh và độ rộng chuyển tiếp
Longpass and shortpass filters are often selected by edge position, but transition width and blocking depth determine real system performance.

Bộ lọc longpass・shortpass
Bộ lọc longpass và shortpass OPTOStokes cung cấp chuyển tiếp cạnh sắc nét để tách bước sóng trong kính hiển vi huỳnh quang・quang phổ Raman・thiết bị quang học. Bộ lọc longpass truyền bước sóng dài hơn cut-on và chặn bước sóng ngắn hơn; bộ lọc shortpass làm ngược lại. Lý tưởng để kết hợp với bộ lọc bandpass khi cần độ chọn lọc quang phổ chính xác.

Tài liệu kỹ thuật liên quan
Kết hợp bộ lọc cạnh
A longpass and shortpass pair can define a custom passband when a standard bandpass option is not available.
Bảo vệ detector
Use edge filters to suppress unwanted source energy before it reaches sensitive detectors, especially in broadband or high-power systems.
Câu hỏi thường gặp
Sự khác biệt giữa bộ lọc longpass và shortpass?
A longpass filter transmits wavelengths longer than its edge; a shortpass filter transmits wavelengths shorter than its edge.
Bước sóng cut-on và cut-off là gì?
It is the edge wavelength where the filter transitions between blocking and transmission.
Có thể kết hợp bộ lọc cạnh với bộ lọc bandpass không?
Yes. Edge filters are often combined with bandpass filters to improve blocking or shape a more specific spectral window.
