DESCRIPTION

 

Speckle patterns from a multimode fiber can cause problems in many applications that require uniform, stable light distributions at the fiber output. The MMS-201 multimode scrambler, a superior replacement for the MMS-101, is specially designed to solve this problem. Based on a General Photonics proprietary technology, the MMS-201 effectively randomizes multimode speckle patterns over time at a high frequency over 20kHz. The light distribution at the output appears uniform and stationary when viewed by cameras or detectors with averaging times >80 ms. In addition, the all-fiber optical path minimizes the scrambler’s insertion loss. The fiber used for this device undergoes a special surface treatment to prevent breakage under stress, ensuring high device reliability.  The MMS-201 can improve performance in various applications including DNA sequencing, multimode fiber sensing and test and measurement of multimode fiber devices.
