Optotune

Transmissive 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-2005 is designed for practical use with your optics table and works together with the LSR-E power supply.

Optotune's laser speckle reducer is the ideal choice for application in:

Laser projection displays
Beam homogenizer
Metrology
Microscopy
Interferometry
Lithography

Results

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.

OEM Version

Unpackaged OEM version

For large volumes (>100 units), Optotune provides a miniaturized OEM version of the LSR with minimal housing. The small size of the OEM version facilitates component integration into at a sub-system (e.g. collimation optics) or system level (e.g. laser projection system).
