Detect Small Amounts of Light Using a Single Fiber Avalanche Photodiodes with Fiber Pigtails

LASER COMPONENTS now manufactures avalanche photodiodes with fiber pigtails.

With a semiautomatic assembly unit, the fibers can be adjusted exactly to

within a few μm and thus achieve coupling efficiencies of almost 100%. The
pigtailing technology is very flexible - almost any combination of APD and
fiber can be implemented: all optical fibers with a core diameter of < 600 μm can be combined with our APDs in a TO-46 housing.

The advantages of fiber coupling are obvious: in medical technology or
analytical measurement technology, it is often not ideal to have the
detector close to the area of measurement; in photon-counting applications,
it is possible to shield disruptive signals with the help of an opaque fiber
jacket; in industry, data is transmitted across very long distances via
optical fibers.

On a standard basis LASER COMPONENTS offers the SAP-series Geiger-mode APDs and the particularly low-noise IAG-series InGaAs APDs. Hermetically sealed
and with high mechanical durability, these APDs exceed the requirements of
the Telcordia GR-468 standard. The development of APDs according to customer
specifications is inexpensive and possible at any time.

SCHUNK's New Safety Gripping System EGN

SCHUNK's New Safety Gripping System EGN

With the SLS, SOS, and STO functionalities, the SCHUNK EGN gripping system certified in accordance with DIN EN ISO 13849 enables safe human/machine collaboration. If the production process is interrupted by an emergency shut-off, the SCHUNK EGN goes into either a safely limited speed mode or a safe stop mode depending on the activated protection zone. In contrast to other solutions available on the market, the SCHUNK safety gripping system is continuously powered even in the safe operating stop so that the gripped parts are reliably held even without mechanical maintenance of gripping force. As soon as the protection zone is released, the gripper immediately switches back to the regular operating mode without the system having to be restarted.
