护目镜快速检测仪的研制

Development of a fast testing device for eye guards

为了加强护目镜的质量控制和缩短护目镜的检测周期,进而保障人眼安全和促进相关产品的出口,在分析国内外护目镜标准中可见光透射比技术要求和测试方法的基础上,依据最新护目镜国际标准中规定的宽光谱光源测量方法,结合产品检测过程中的实际需求,研制一台护目镜快速检测仪;利用标准镜片对该检测仪进行校准。研究结果表明:不同国家标准对护目镜可见光透射比的技术要求和测量方法均有差异;校准结果符合国际标准中对检测设备精度的要求;所研制的检测仪的可见光透射比测量精度高、速度快,可作为标准检测设备广泛应用于生产企业、检测机构和终端用户。

In order to improve quality control of eye guards and reduce testing period so as to guarantee safety of human eyes and promote export of products,luminous transmittance requirements and testing methods in domestic and foreign standards were analyzed.Then, based on broadband light source measurement method stipulated in the latest published international standard,a fast testing device was developed according to actual demand.Finally,it was calibrated by standard oculars.The results show that luminous transmittance requirements and testing methods vary significantly in standards of different countries.The newly developed testing device is accurate and fast,so it can be widely used as a standard testing instrument to measure luminous transmittance for eye guards.
