How to Choose

Select the center wavelength around the source or target signal, then choose the narrowest FWHM that still allows enough usable signal. Confirm OD blocking, peak transmission, AOI sensitivity, temperature range, and physical tolerance.

Narrow Bandpass Filters

These narrow bandpass filters (CWL 405-808nm) provide precise wavelength selection with FWHM as narrow as 1nm and OD6+ out-of-band blocking. They are suited to Raman spectroscopy, laser clean-up, confocal microscopy, and high-sensitivity fluorescence detection where wavelength purity is critical.

Related Engineering Notes

When narrow FWHM is worth the tradeoff

Narrower bandwidth improves wavelength discrimination, but it can reduce throughput. It is most useful for laser cleanup, spectral analysis, and tight emission lines.

Blocking outside the passband

For high-sensitivity detectors, OD outside the passband can matter as much as peak transmission. Confirm the blocking range, not just the center wavelength.

Custom CWL requests

If a catalog wavelength is close but not exact, specify target CWL, tolerance, FWHM, blocking range, and working angle in the quote request.

FAQ

When should I choose a narrow bandpass filter?

Choose a narrow bandpass filter when nearby wavelengths must be rejected, such as laser cleanup, fluorescence detection, Raman, and high-sensitivity instruments.

Does a narrower FWHM always perform better?

Not always. Narrower filters improve selectivity but may reduce signal tolerance if the source drifts or the angle of incidence changes.

Can narrow bandpass filters be made at custom wavelengths?

Yes. Custom CWL, FWHM, blocking range, size, and substrate options are available for OEM requirements.
