EN 207 is split into four protection categories: D for continuous wave lasers; I for pulsed lasers (100ns to 0.1s pulse duration); R for Q-switched lasers (1 to 100ns) and M for mode-locked lasers (less than 1ns).
Laservision is one of the first manufacturers of safety spectacles worldwide to demonstrate that its eyewear meets the mode-locked specification of European laser eyewear standard EN 207.
A broad range of certified products for use with ultra short pico- and femtosecond lasers is offered. The filters are made from ion-doped mineral glass; some of them with additional di-electrical coatings for even higher laser resistance and better colour recognition.
