What is an optical distractor?
According to the US Government, non-lethal Optical Distractors (ocular interrupters or “laser dazzlers”) are visible (green) laser devices that have temporary optical effects on human targets. These types of non-blinding laser devices use highly directional optical energy to support several non-lethal missions, including:
- Temporarily overwhelming an adversary's visual sense by emitting a compelling glare source.
- Providing an unequivocal non-verbal warning.
- Providing the target an opportunity to clarify intent.
Although these mission capabilities are generic to any high-intensity light source, laser light sources, versus LEDs, are ideal for non-lethal applications, as the optical energy is collimated and very directional. This allows the Operator to precisely deliver the laser energy at long ranges, while minimizing the total power output and minimizing collateral effects to other bystanders.
What is the intended use for the Dazer Laser®?
A Dazer Laser® allows the Operator to temporarily impair the vision of the target(s) by temporarily eliminating their ability to see, engage and/or effectively target the Operator by overwhelming their visual sense. Due to the Operator’s ability to adjust the range of engagement from 1-2400 meters (model dependent), the Operator can visually impair, warn, assess, deter, suppress, illuminate, target, hail and warn, and/or communicate with the target(s) potentially avoiding an unnecessary escalation to more lethal engagements.

What does NOHD mean?
NOHD is an acronym that stands for Nominal Ocular Hazard Distance. The NOHD represents what a laser system’s eye safety zone is. For example, if a laser system has an NOHD of 20 meters, the system cannot be used eye safe from the exit point of the system out to 20 meters in range. Beyond 20 meters, no eye damage will occur.
What is MEAN Beam™ Technology?
The patent pending MEAN Beam™ technology is incorporated into all Dazer Laser® Products. MEAN Beam™ technology is a unique way of operating the GreenStar Laser in a simultaneously CW (continuous wave) and pulsed (modulated) lasing mode out of one laser. This provides the Operator with a certain combination of CW and chirp modulated (6-16 Hz) lasing for different Day Time or Night Time modes.
Previously, Optical Distractors have functioned in either a CW (continuous wave) mode, Slow Pulse mode or Fast Pulse mode which has different effects on the target in daytime versus nighttime operations. During the day, since the sun acts as the most powerful source of surrounding ambient light, the pupil of the human eye is smaller in diameter to help prevent too much light from entering the eye and potentially causing damage. Since the pupil is smaller, the laser would operate in the CW only mode to apply more irradiance to the human eye while constricted in the day. During the night (low-light), since there is a significantly less amount of ambient light available, the pupil of the human eye is much larger in diameter which allows more light to enter the eye to compensate for the lack of surrounding ambient light. Being the pupil is larger and allows more light into the eye, these other Optical Distractors would operate in a pulsed mode.

Why the color green versus red or other colors?
The Dazer Laser® GUARDIAN operates at the 532 nm (nanometer) wavelength, or the color Green. The diagram below shows where different wavelengths, or light, can be seen or not seen by the human eye. Because the color Green (in the center of the Visible part of the spectrum) is furthest from both UV and IR (invisible) wavelengths, the human eye sees the color Green better than any other color.
Green Lasers are seen anywhere from 4x – 300x greater than Red, or any other colored, Lasers.
Who can buy Dazer Laser® Products?
All Dazer Laser® Products are restricted to active duty Military, Law Enforcement and Government affiliated Security Agencies. No Dazer Laser® Product can currently be sold to the civilian population.
