Wavelength selection

Broad Bandpass Filters

Keep a wider band.
Look at the whole response.

Start with the wavelength interval you want to retain. Compare both edges and the response inside that interval to find a useful starting design.

FIND YOUR STARTING POINT

How to choose
within this family.

01

Define both ends of your useful band

Identify the shortest and longest wavelengths your system needs to retain. Compare both boundaries with each model’s curve, rather than selecting by the peak wavelength alone.

02

Compare transmission across the band

A high peak does not mean every wavelength passes equally. Check transmission at your important wavelengths and review the shape between them. FWHM describes width at half the peak, not a uniformly transmitting region.

03

Check what else reaches the detector

Inspect secondary transmission regions and the response outside your useful band. A wider passband can also admit unwanted light within it; compare the complete measured curve with your source and detector.
