Optotune offers transmissive laser speckle reducers with high transmission. ​ 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. ​ ​ LSR-3000 Series ​

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.

For large volumes (>100 units), Optotune provides a miniaturized OEM version of the LSR with minimal housing called LSR-OEM.

​

The small size of the OEM version facilitates component integration into a sub-system (e.g. collimation optics) or system level (e.g. laser projection system).
