Laser Speckle Reducer
The LSR Series allows you to significantly reduce the speckle noise of laser systems. Local interferences are removed by dynamically diffusing the coherent beam. The LSR-3000 is designed for practical use with your optics table and integrates fully certified drive electronics powered through a single micro-USB connector.
Optotune's laser speckle reducer is the ideal choice for application in:
- Laser projection displays
- Beam homogenizer
The following figure shows typical images of the speckle contrast measured on a reference setup with and without LSR. The colored lines show the cut planes that correspond to the intensity plot.

This video demonstrates the speckle reduction effect in a reference setup with a red laser (650nm, 5mm beam diameter). The laser spot is imaged using a standard CCD camera. (download mov-file)
