Condition monitoring sight glass with remote sensing ports

An apparatus for machine fluid monitoring comprising:

• a sight glass at least partially constructed of one or more material that is transparent to light in a visible region, the sight glass having an open first end, a closed second end constructed of the one or more material that is transparent to light in the visible region, a sidewall constructed of the one or more material that is transparent to light in the visible region and extending between the open first end and the closed second end, and an inside surface and an outside surface extending from the open first end to the closed second end and at least partially surrounding a cavity within the sight glass, wherein the open first end of the sight glass is configured to be attachable to a machine such that machine fluid is transferable from the machine to the sight glass, the sidewall of the sight glass further having at least one remote sensing port constructed of the one or more material that is transparent to light in the visible region and between the inside surface and the outside surface, the inside surface and the outside surface of the remote sensing port being aligned, and convex in shape such that objects inside the sight glass are magnified, the inside surface and outside surface of the sidewall adjacent to the remote sensing port being shaped to permit viewing within the sight glass but provide optical properties different from optical properties within the remote sensing port.
