L E SYSTEMS, INC. BACKS ITS PRODUCTS WITH THE EYES OF ITS OFFICERS.

On March 27, 2008 and May 29, 2008 eye examinations of the two individuals with the most exposure time to the CHP Laser Dazzler™ were conducted by a retinal specialist. The report states “There is absolutely no damage to any part of the eye from any type of light or laser exposure.” and “There is absolutely no evidence of any problems from any type of light or laser exposure.” Click here to view the Chart Notes in PDF format. The complete eye examination results, including retinal scans are available upon request.

Background: It was recognized by L E Systems, Inc. after initiating work on a DARPA contract in 1996, that a new eye safe power density should be established for human use of lasers as a TEMPORARY vision impairment device. In late 1999, L E Systems was also encouraged by the USMC expert on non-lethal devices to proceed with this determination.

The power density established by L E Systems is greater than the ANSI Z136.1 calculated number 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.

The L E Systems' proprietary eye safe power density offers a large margin for safety against any possibility of permanent eye damage when using our products in accordance with the instructions provided.

* The NOHD values were determined based on actual CHP power density measurements. Since a true NOHD CANNOT be determined without power density measurements for the basis, the CHP NOHD values determined by the independent laboratory represent the only credible NOHDs for CHP. The unit tested exhibited the highest power density of any CHP produced to date.

(NOHD with LE provide diffuser 5 meters)

These NOHD values are being provided as reference only and for those whose authorizing agency require adherence to the ANSI/IEC eye safe criteria for use of such devices.

As stated in CHP page of this web site, the LE Systems proven safe minimum stand off distance remains at 20 meters.

The original baseline and subsequent examinations were conducted on January 4, 2002 and July 15, 2005 and state no eye damage.
