A tube fitting including a first fitting member having a cylindrical body including a flange, a second fitting member having a cylindrical body including a plurality of tines extending from the cylindrical body, the plurality of tines being configured to engage the flange where the plurality of tines and the flange are configured to secure the first and second fitting members to each other, and at least one seal disposed between the first fitting member and the second fitting member.

Tube fitting

Planar waveguide spectrograph

An optical source for use in an optical sensing system such as a wavelength division multiplexing system. The source produces an optical interrogation signal comprising a plurality of component signals, each component signal comprising light in a wavelength band different from the wavelength bands of the other component signals. The source comprises a concave diffraction grating, means for forming an aperture at which the interrogation signal will be formed, and a plurality of optical emitters. Each emitter is positioned such that the emitter output signal strikes the concave diffraction grating, and is focused onto the aperture, such that a portion of the emitter signal enters the aperture and forms one of the component signals. As a result, the component signal wavelengths are not sensitive to temperature-induced fluctuations in the emitter output signal.
