Carruthers is considered the inventor of the ultraviolet camera/spectrograph.
His work with the spectrograph also demonstrated incontrovertible proof that molecular hydrogen exists in the interstellar medium.

In 1964, Carruthers began employment for the U.S. Naval Research Laboratory in Washington, D.C., where his work focused on far ultraviolet astronomy.
1969 was the year he received a patent for his invention, the "Image Converter," which detected electromagnetic radiation in short wavelengths, and in 1970, he made the first examination of molecular hydrogen in space.

Two years later, Carruthers invented the first moon-based observatory, the Far Ultraviolet Camera/Spectrograph, which was used in the Apollo 16 mission.
In 1986, one of Carruthers' inventions captured an ultraviolet image of Halley's Comet.
In 1991, he invented a camera that was used in the Space Shuttle Mission.
