Narrow Bandpass Filters
PRODUCT CATEGORIES
INOUIRY
The transmission band of the bandpass narrowband interference filter is surrounded by two cut-off bands. It only allows part of the wavelengths in the spectrum to pass through. It is often used to transmit part of the spectrum while cutting off all other wavelengths. Suitable for a variety of applications such as spectroscopy, clinical chemistry or imaging. Bandwidth is the spectral range of the illumination light transmitted by an optical filter. The bandwidth/ FWHM of narrowband filters are usually ＜20nm
