Bandpass Filters

figure Bandpass Filters

Bandpass filters are commonly used to transmit a well-defined wavelength band of the spectrum while rejecting both the long and short wavelength sides of the transmission band. Our coating designs are based on multiple cavity resonators. Thus, our bandpass filters have very steep slopes and very high attenuation outside of the narrow pass 10nm band. Asahi Spectra offers a wide variety of bandpass filters in the broad wavelength range: ultraviolet, visible, or infrared wavelengths.
