The transmitted band of bandpass filter is surrounded by two cut-off bands. They are used to pass through partial wavelength and block all other wavelengths. Bandpass Filters are ideal for many applications, such as spectroscopy, clinical chemistry, or imaging. Image Optics provides a variety of half-bandwidth bandpass interference filter with a variety of transmission and sizes to suit your application.
