OPTOStokes là thương hiệu bộ lọc quang học của Optofilters.com, cung cấp bộ lọc có sẵn và bộ lọc phủ tùy chỉnh cho các ứng dụng UV, VIS, NIR và IR.
So sánh dải truyền hẹp theo bước sóng trung tâm・FWHM・mức chặn sáng・độ dày. Các bộ lọc này dành cho ứng dụng mà độ chọn lọc phổ quan trọng hơn thông lượng.
Chọn bước sóng trung tâm của nguồn sáng hoặc tín hiệu mục tiêu, sau đó chọn FWHM hẹp nhất vẫn đảm bảo đủ tín hiệu khả dụng. Cũng kiểm tra chặn OD・độ truyền qua đỉnh・độ nhạy góc tới・dải nhiệt độ・dung sai vật lý.
Các bộ lọc bandpass băng hẹp này (bước sóng trung tâm 405–808nm) cung cấp lựa chọn bước sóng chính xác với FWHM từ 1nm và chặn sáng ngoài dải OD6+. Phù hợp cho quang phổ Raman・làm sạch laser・kính hiển vi đồng tiêu・phát hiện huỳnh quang độ nhạy cao, nơi độ tinh khiết bước sóng là yếu tố then chốt.

Narrower bandwidth improves wavelength discrimination, but it can reduce throughput. It is most useful for laser cleanup, spectral analysis, and tight emission lines.
For high-sensitivity detectors, OD outside the passband can matter as much as peak transmission. Confirm the blocking range, not just the center wavelength.
If a catalog wavelength is close but not exact, specify target CWL, tolerance, FWHM, blocking range, and working angle in the quote request.
Choose a narrow bandpass filter when nearby wavelengths must be rejected, such as laser cleanup, fluorescence detection, Raman, and high-sensitivity instruments.
Not always. Narrower filters improve selectivity but may reduce signal tolerance if the source drifts or the angle of incidence changes.
Yes. Custom CWL, FWHM, blocking range, size, and substrate options are available for OEM requirements.
Quality & Compliance
For OEM programs, laboratory instruments, and industrial systems, OPTOStokes keeps quality, material compliance, and engineering support visible from the start of supplier evaluation.
Process control, inspection records, and repeatable coating workflows for production optical components.
Compliance documentation can be prepared for qualified projects and regulated supply chains.
Wavelength, FWHM, substrate, AOI, size, and mounting requirements can be reviewed with engineering.
Share target wavelength, blocking level, transmittance, and drawing requirements for a focused quote.
Our engineers will help you select the perfect optical solution.
