The laser classification categorize laser sources according to their ability to produce damage to the human eye. Z-LASER validates and tests each laser source according the DIN standard 60825-1. The test setup simulates the structure of a human eye at complete darkness.
Using a multiaxial setup, the laser beam profile is sent through a standardized whole of 7mm diameter. The passed light is collimated and the power measured. The maximum power measured through this setup defines the laser class according to the intensity limits defined in the DIN standard.
