How is laser power specified in Laserworld projectors?

Laserworld always specifies power directly at the laser source. This is done due to the fact that optical elements, like dichroic filters, polirization cubes or the front glass deflect light differently and may get dirty as well. As Laserworld guarantees the minimum specified power value given for their projectors directly at the laser source, customers may claim if the values are not met. In fact, this usually does not happen due to the 100% quality control, where the power values are measured and evaluated.
