浅析激光指示器的危害及安全要求

Analysis on the Harm and Safety Requirements of Laser Pointer

激光指示器广泛应用于日常生活中的多种场合。文章介绍了激光指示器的激光等级分类及激光可达发射功率的测试,详细阐述了消费类激光指示器的安全要求。通过实测购买的15个品牌的激光指示器,发现市场上大功率激光指示器的比例在80%以上,且存在激光标识不清晰或错标等现象。基于消费者不了解高功率激光指示器危害的现状,建议制造商在生产阶段严格控制激光指示器的功率输出,考虑产品最严酷的工作状态并依据GB/T 7247.1-202X进行激光等级的判定,在本体醒目位置上标识激光说明和警告,并通过公益科普培训等形式,提高消费者对激光的认知水平。

Laser pointer is widely used in many places in daily life.This paper introduces the laser level classification of laser pointer and the test of laser accessible emission,and expounds the safety requirements of consumer laser pointer in detail.By testing 15 brands of laser indicators,it is found that the proportion of highpower laser indicators in the market is over 80%,and there are some phenomena such as unclear laser labels or wrong labels.Based on the fact that consumers don't know the harm of high-power laser pointer,it is suggested that manufacturers strictly control the power output of laser pointer in the production stage,the most unfavorable working state of the product should be considered when laser classification according to GB/T 7247.1-202X,marking laser instructions and warnings on the product body,and consumer's cognitive level of laser should be improved through public welfare training.
