The nature of light emitting sources used in products mandates worldwide compliance to Optical Radiation Regulations. This document addresses products contain-ing light emitting sources with sufciently low levels of optical radiation in a selected wavelength range. Since eyes only may be at risk, we refer to "eye safety" in this white paper, rather than optical radiation safety. The laser used as a light source in an optical mouse must meet eye safety regulations and be correctly classifed in order to safeguard user safety and prevent any untoward incidents that can seriously harm the user. A product that is incor-rectly classifed to be safe, and emits radiation accessible to a viewer above the Class 1 level can cause irreversible damage to the viewer’s retina.Laser Navigation Eye Safety Classification
