可见光和近红外线本阈限值是针对波长在４００ｎｍ～３０００ｎｍ的可见光和红外辐射。认为在这种条件下，几乎所有的工人接触，不产生对健康的损害作用。这些值来自于实验研究，只能作为控制接触可见光的指南，不能作为划分安全与否的分界线。为了说明这些阈限值，在表１... Visible and near infrared The threshold is for visible and infrared wavelengths in the 400nm ~ 3000nm. It is believed that under such conditions, almost all workers will be exposed without any health damage. These values ​​come from experimental studies and should only serve as a guideline for controlling exposure to visible light and should not be used as a delineation of safety or not. To illustrate these thresholds, in Table 1 ...
