Fiber Optic Probes and Cables

FeedthroughPurposeDetailed descriptionThe three types of fiber optic probes Lake Shore offers
SMAGeneral purpose/low costSMA 905/906 with flat end (<-11 dB return loss connected); hermetic feedthrough has air gap transition from external customer fiber to internal probe fiber
FCHigh performance/low optical lossNTT-FC with super PC polish (-40 dB return loss connected); hermetic feedthrough is matched to the fiber type for transition from external customer fiber to internal probe fiber
PenetratingIntegrated fiber and feedthrough to maintain polarizationFiber is epoxy sealed to the feedthrough and is continuous through the vacuum chamber to maintain polarization; fiber extends 0.4 m from top of probe arm base with FC style connector on the user end
