Lenses are sometimes added to fiber optic assemblies for extending opposed mode sensing range. Banner ofers the following lens
assemblies for use with fiber optic assemblies which have 5/16” -24 threaded sensing tips (e.g. fiber model IT23S):
Lenses are most efficient when they are located slightly beyond their focal length distance from the sensing end of the fiber optic
bundle. The easiest way to focus a lens is to treat it like a magnifying glass.
Illuminate the fiber optic bundle at the threaded end of the fiber optic assembly by directing the opposite end toward a visible light
source (e.g. - an incandenscent bulb, visible LED, sunlight, etc.). Thread the lens onto the fiber optic assembly until the end of the
fiber optic bundle comes into sharp focus under the lens. Then, back off (unthread) the lens assembly from the point of sharpest
focus by one to three full turns. The illuminated bundle should now appear slightly blurred. This is the optimum setting, and the
lens may be secured in position using one of the jam nuts provided. Refer to the drawing above.
