Fiber-optic assemblies

Plastic and glass fiber-optic assemblies are encapsulated in FEP Teflon to withstand harsh chemical environments and chemicals, including the severe acid bath presented in semiconductor wafer manufacturing applications. The standard plastic models feature an operating range of -22 to 185F, and for HT1 plastic models the range is from -22 to 257F. The assemblies are available for opposed, through-beam sensing using a separate emitter and receiver, with or without lenses. They are also for diffuse-mode sensing using bifurcated fibers that emit and receive light signals in the same assembly.
