With these photodiode sensor accessories, you can adapt your free space detector to accept connectorized or bare optical fibers. Because the beam coming out from the fiber is divergent, it is important to consider the distance between the fiber tip and the sensor size. In order to make accruate measurements, the beam diameter must be smaller than the active diameter of the sensor. The new 884 series fiber adapters are screwed directly onto the sensor head, while the FP3/FP4 series adapters require an additional fiber adapter mount, either 818-FA or 818-FA2. For low power measurements, consider our 818 Fiber-Optic Photodiode Sensors. When you use an 818 series with the attenuator on, or a 918D series sensor, please refer to the diagram on the right. 

FP3/FP4 Series Connector Adapters accommodate optical fibers with SMA, ST, FC, SC and LC connectors. The adapters are attached to the 818-FA Fiber Adapter Mount with two screws. Use these adapters, together with the FP4-COL-1550 collimator, when you need to use the attenuator with the germanium or InGaAs detectors to measure > 10 mW power. As an example, the video shows how to properly insert the FP4-COL-1550 into an FP4-LC Fiber Connector Adapter.

918D-IS-SMA, 22494-01S, 31850-01S, 31856-01S and 22493-01 are compatible with our 918D-IS Series Fiber-Optic Integrating Sphere Sensors. These fiber optic connector adapters accommodate optical fibers terminated with SMA, FC, LC, LC or ST connectors. 

CA100, CA150 and CA20001 are compatible with our ILX Lightwave® FMH Series Fiber Optic Power Sensors and Power and Wavelength Measurement Head. These fiber optic connector adapters accommodate optical fibers terminated with FC, SC or LC connectors.
