altOPTRA (Topsfield, MA) offers a laser event recorder that measures, characterizes, and documents laser exposures in support of dosimetry requirements for the protection of personnel working with, or who could potentially be exposed to, laser illumination. The laser event recorder is battery powered and operates for six hours against continuous and pulsed laser sources in the visible and near-infrared portion of the spectrum. The recorder detects laser energy, extracts exposure information such as irradiance level, wavelength, pulse duration, pulse repetition frequency, time and location of exposure, and captures an image of the scene containing the laser. Irradiance levels are compared to the appropriate ANSI standard to determine if the exposure level poses a hazard to eye safety.
