Abstract
The evaluation of the direct beam laser hazards primarily consists of the determination of the NOHD with and without the use of optical devices, and the necessary optical density (OD) required for laser eye protection. The required OD would depend on whether the viewer was located at the laser exit or at a location downrange from the laser. Intrabeam viewing of a laser with optical devices generally requires a higher OD than viewing with the naked eye since more laser energy is collected by the optics. The NOHD of a specularly reflected laser beam must be determined if specular reflectors may be located where the laser beam is pointed.
