WebIn addition to impacting damage threshold, scattered high-power laser radiation can be a safety hazard for anyone near the system, as the light is being redirected in unintended directions. The current standard utilized for surface roughness is ISO 10110-8, which defines how surface roughness should be analyzed and specified.
The optic radiation contains tracts which transmit visual information from the retina of the eye to the visual cortex. Lesions of the optic radiations are usually unilateral and commonly vascular in origin. Field defects therefore develop abruptly, in contrast to the slow progression of defects associated with tumors.
