Speckle is a random granular pattern commonly observed in the output beam of a laser. It is characterized by many dark and light spots of different intensities visible in a given cross section of the laser beam. This effect occurs as a result of interference between various propagation modes of the light.
The reduction of speckle is important for applications where a homogeneous laser output of uniform intensity is ideal, such as laser-scanning microscopy, flow cytometry, and DNA sequencing. By using Fiberguide’s De-Speckler to average the modal noise and greatly reduce speckle, maximized performance can be achieved. Other benefits resulting from speckle reduction can include faster integration times, improved signal-to-noise ratios, and higher throughput.
Our speckle reduction solution has a small form factor and is in-line with a customizable fiber assembly. The fiber size, core shape, jacketing, connectors, and length can all be customized to perfectly suit your application. Please view the product specifications for more information.
