How do you rate output laser power?

The output power of a laser is the maximum power of the light exiting the the laser housing. All World Star Tech lasers have their output power rated after passing through any installed optical assemblies. The power is measured according to CDRH specifications.

Each laser is classified by measuring the amount of optical power that would enter a 7mm aperture located at a distance of 20cm from the laser source. Our line lasers have a lower classification rating because the laser power is spread along the length of the line, rather than focusing on a single small point.
