Jetlasers portable laser dazzlers are made and tested with a precise eye safe power density for mere TEMPORARY vision impairment device. However, the power density established by Jetlasers is a little greater than the standardized ANSI Z136.1 power density of 2.55mW/cm² for a cw laser based on a 0.25 second exposure time (blink response). 2.55mW/cm², the maximum allowed (MPE) by ANSI Z136.1 to be designated eye safe, is 10% of the power density (26mW/cm²) necessary to cause irreversible eye damage, based on a 0.25 second exposure time.

NOHD [Nominal Ocular Hazard Distance] for direct intrabeam viewing is the distance beyond which an unprotected person may stand in the beam with a naked eye and be exposed without injury. It is extremely important to be aware of the NOHD when operating a laser. If you are unsure of the NOHD, then you presume it is the distance of the size of the room the laser is operating in, and that anywhere in the room is within hazard distance if laser light accidentally hits the eyes

JETLASERS’ portable laser dazzlers products are mainly for law enforcement use. We welcome trained and certified police and security personnel with open arms. We also provide FDA complaint laser dazzlers to those who purchased it for self defense purposes.

Lasers are dangerous. Laser light from laser pointers can potentially burn the retina of the human eye. The danger is obviously greatest if the beam is aimed directly into the eye, rather than merely scattered from the beam and seen from the side. The danger is dependent on the wavelength of the laser light, the power of the laser pointer, the divergence of the laser beam, the distance of the person from the pointer, whether the beam is seen directly or via a reflection, how long the beam is viewed and whether the human eye’s natural ‘blink response’ to bright light occurs.

In most all laser safety and compliance standards, the output aperture, a, and the beam divergence, (PHI), are defined relative to the e(-1) points. The total laser energy (Q(t)) or beam power (PHI) is defined as that which is collected from the entire beam (total values).

Many manufactures specifications use the e(-2) i points to define beam divergence. In this case, e(-2) i = 0.1353, or the total power (energy) is: 100% - 0.13 3 x 100% = 86.47% or approximately 86% of the total energy /power is within the e(-2) aperture. In some cases, they specify relative to the 90% point. Note that the beam divergence is larger at the e(-2) or 90% point. Hazard calculations are sensitive to the beam divergence and conversions from e(-2) points to e(-2) power points are often performed on beam sizes.
