NOMINAL DISTANCE TO AVOID OCULAR HAZARD(DNRO)
FOR AN EXPOSURE TIME OF (Seconds): 0.25
Minimum safe distance in this case*
191 mm
* Consider as Hazard Zone Optics (NRA), or area within which the irradiance or radiant exposure exceeds the
maximum permissible exposure (MPE), all positions within an envelope of the remote DNRO.
Information:
Exposure time is fixed to 0.25s for this calculation table, which is the latency blink of the eye duration.
Output power: The maximum output power for the type of LED used in the product is 39 Lm under 350mA.
Number of Led: In the worst case, we can imagine that the person can see entirely the light.
