Bandpass filter

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

The bandpass filters are available in two standard sizes:

• Round with a diameter of 25 mm
• Square 50×50 mm
