Abstract
A speckle reduction instrument having a parabolic reflector and flat mirror to form a cavity-based unit. Laser light is collected and bounced around the cavity hitting a diffuser surface multiple times. The laser light that is highly coherent is converted into less-coherent but still bright light suitable for illumination in microscopes and other devices. Also disclosed is the related method for reducing speckle.
