214nm bandpass filter is an optical filter that transmits only a narrow range of wavelengths centered around 214nm and blocks all other wavelengths. It is typically made of a material with a high refractive index and coated with thin films of dielectric materials that selectively reflect or transmit light.

In addition to UV spectroscopy, 214nm bandpass filters also have applications in microscopy, lithography, and other areas of science and engineering that involve the manipulation of UV light.
