Reduced coherent optical noise

T

he Lasiris™ Reduced Speckle Line Generator significantly diminishes the speckle content which is apparent in standard industrial lasers, therebyincreasing the accuracy of machine vision profiling applications. With its low coherence length, the module provides low speckle noise while maintainingtight focusing performance. Furthermore, it is thermoelectrically cooled, offering longer lifetime and excellent wavelength, power and pointing stabilities.
