Use the FJW Speckle Buster to reduce the speckle phenomenon.
The 85615 Speckle Buster® helps you to see the true nature of your laser beam.
Coherent sources such as laser beams, exhibit a phenomenon known as speckle. Speckle manifests itself as a coarse granularity in a beam intensity pattern. For beam profiling , or for laser mode determination, speckle masks the true nature of the beam intensity profile. By the use of the Speckle Buster® the true beam intensity profile is revealed.
Also when two laser beams are allowed to interact, as in an interferometer, (a metrology instrument utilizing the wavelength of light as a length standard) the resulting pattern, called an interferogram, also suffers from speckle. A laser interferogram may be totally unreadable in the presence of speckle. With the use of Speckle Buster the true profile of such interference pattern is produced. |
