1. An optical fiber assembly for use in a biological environment comprising:

  • an elongated physiologically toxic optical fiber having ends, said fiber being at least partially transparent to radiation at infrared wavelengths;

    a physiologically nontoxic sheath surrounding said optical fiber adjacent at least one end thereof, said sheath being tubular with a bore therein extending beyond the end of said optical fiber, said sheath being made of malleable stainless steel material, said sheath bore having a swaged divergent interior surface adjacent the end of said sheath; and

    a window within said sheath adjacent said end of said optical fiber, said window being physiologically nontoxic, said window being at least partially transparent to radiation at infrared wavelengths, and having a convergent swaging exterior surface resiliently engaged against and within said divergent swaged interior surface of said sheath bore to hermetically seal and plug the end of said tubular sheath without soldering, said sheath resiliently embracing and engaging said window, said window being at least partially transparent to radiation of the same wavelength to which said optical fiber is at least partially transparent.
