Neither the international laser safety standard IEC 60825-1 Edition 3.0 nor the standard ANSI Z136.1-2014 provide specific rules on how to apply the pulse reduction factor C5 (resp. CP) to irregular pulse trains, featuring both varying peak power as

According to current ANSI Z136.1, IEC 60825-1 and ICNIRP guidelines, two exposure limit criteria apply for the cornea and skin: the single pulse limit and the average irradiance limit. The reduction factor CP for repetitively pulsed exposures need on

A computer model that predicts thresholds for laser induced corneal injury in the infrared wavelength range was used to systematically analyze wavelength, pulse duration and beam diameter dependencies. The thresholds were compared with the respective

In the wavelength range of 400 nm to 1400 nm, the retinal thermal exposure or emission limits depend on the angular subtense of the apparent source (Greek symbol “alpha”). For the case that a given laser beam is associated to an extended source,

The international lamp safety standard IEC 62471 “Photobiological safety of lamps and lamp systems” defines criteria to classify lamps into one of four risk groups (exempt, RG1, RG2, RG3). RG3 is referred to as “high risk” and is usually not

In this paper, we report on two European laser safety standardization projects that will lead to European standards without corresponding IEC documents. In one project, an amendment A11 for EN 60825-1:2014 is developed. The amendment can be seen as c

The exposure and emission limits of ICNIRP, IEC 60825-1 and ANSI Z136.1 to protect the skin are based on a limited number of in-vivo studies. To broaden the database, a computer model was developed to predict injury thresholds in the wavelength range

The current laser safety standards do not address specifically how to account for repetitively pulsed lasers with irregular pulse trains. Variations in peak power, pulse duration, and duty cycle within a pulse train pose a number of problems when it

Neither the international laser safety standard IEC 60825-1 Edition 3.0 nor ANSI Z136.1-2014 provide specific rules of how to apply the pulse reduction factor C5 (CP) to irregular pulse trains. Without specific guidance, the analysis has to be perfor
