They are used to isolate certain wavelengths or colors. Applications range from detecting the gaseous composition of a distant star to visualizing the chemical activity in a human cell. Ultraviolet (UV) bandpass filters (with effective wavelength ranges below 400 nm) pose unique design and manufacturing challenges related to the absorption of materials at short wavelengths.In their earliest forms, UV bandpass filters that were optimized for wavelengths less than 400 nm, such as the Schott UG or the Hoya U-series, were constructed of absorbing compounds in glass.
