Do the fast photodiode detectors (FPD & FPS-1) have attenuators and fiber adapters available for them?

Yes, there are a variety of accessories such as attenuators and fiber adapters available for the FPD & FPS-1 Fast Photodiode Detectors. Fast Photodiode Detectors are used for displaying temporal pulse shape on an oscilloscope. Please note that in order to mount these accessories to the FPS-1 you will need the SM1-to-M20 adapter 1G02259. This is mentioned in the catalog spec page but is sometimes missed. No adapter is needed for FPD models.

To connect a fiber to an Ophir sensor, why do I need 2 items – an “Adapter” and a “Mounting Bracket”

The idea is used with most (though not all) sensors; the fiber optic connectors are standard (such as FC, SMA, etc.), but the sensors are all different in their mechanics, so we use the standard FO connectors but provide in addition mounting brackets for connecting the FO connectors to the various sensors.

Fiber Adapter accessory

When using a Fiber Adapter accessory together with one of Ophir's sensors, it is important to be aware of the power/energy density that is going to reach the sensor's surface.In most cases, the fiber adapter locates the fiber tip far enough away from the absorber surface that the spot diameter on the surface will be large, and problems of damage avoided. However, that is not always a certainty! For example, when using a sensor from the PD300 series, especially with filter IN, this distance could be quite small. A power level that is within spec limits could still result in a power 詳細を見る

Measuring Power out of a Fiber

We recently came across an interesting customer problem, in which every time he disconnected the FO connector from the adapter (that is mounted on the sensor) and then reconnected it, the power read about 50-100 uW higher than it did (nothing else changed). It then took about 10 minutes to slowly come back down to what it had been. After an investigation, we found that the increase in reading when disconnecting/reconnecting the fiber connector is a thermal effect, and not a technical flaw in the unit. If you experience something like this, the most likely direct cause is one of the following 詳細を見る
