비파괴식 검사를 통한 선글라스의 품질에 관한 연구

다국어 초록 (Multilingual Abstract)

In this study, we compared the properties of 23 high and 55 low price sunglass lenses with the standards in the ordinary optical properties. materials, coloration, UV. IR and luminous transmittance, color acceptance for traffic signal, chromaticity and contrast sensitivity. The ordinary optical properties of the lenses met comparatively the requirements of the KS standard. The HIGH-type and LOW-type lenses were primarily made by glass and acrylate, respectively. In the coloration, HIGH-type was in group around neutral color but LOW-type was distributed widely on the line between 570 nm and 485 nm. There are fails in 7 of HIGH-type and 18% of LOW-type in the stimulus purity of the luminous transmittance. Wavelength of the UV/VIS cut-off was over 350 nm for HIGH-type but 6 of LOW-type was under 350 nm. In the erythemal UV, all HIGH-type met the needs of standards but 5 LOW-type failed with DIN standard. In the near UV, KS standard worked in stringency, and HIGH-type showed more failure than LOW-type. The characteristics of the IR transmittance of HIGH-type was better than that of LOW-type. In the color acceptance of traffic signal, all HIGH-type met the needs of ANSI standards but 21.8 of LOW-type failed with the standard. In the contrast sensitivity tested with various coloured sunglasses, the value increased with increasing of L and decreasing of test distance. In view of the results so far, HIGH-type met with excellent properties as compared with LOW-type.
