The Properties of the Absorption Spectra in Tinted Material of Lens and Color Lens

렌즈 염색제와 칼라 렌즈의 광흡수 특성

The optical absorption spectrum was measured of the tinted powder, tinted solution and tinted lens in the visible regions. The tinted powder was very different with color of tinted lens that the optical absorptions was so higher, composed of the thick-gray color. The optical absorptions of tinted solution were just a little appeared by the energy split of a transition metal ion, so constructed with each color space. The optical absorptions of the tinted lens were appeared with the energy split peaks to a transition metal ion, so its were affected by the color constructions. The optical absorption peaks of each lens were depend on the tinted time. Blue color lens had a lot of absorption in the short wavelength regions than 500nm, and had a little appeared in the high wavelength regions than 500nm. In case of a yellow color, the optical absorptions were appeared quite contrary to the blue color, so these colors had the opponent-colors each other. In case of green color, the optical absorptions had a high in the both edges, had a low in the middle regions. In the pink color, by the optical absorptions form of quite contrary to the green color it, these colors had the opponent-colors each other. In the brown color, the optical absorptions had a maximum values in the short wavelength regions, and it gradually decreased goes by the long wavelength regions.

렌즈 염색 powder, 염색 solution, 염색 렌즈에 대한 가시 광 영역에서 광 흡수 spectrum을 측정하였다. 염색 powder는 광 흡수가 높아 염색렌즈의 색과 전혀 다르고, 짚은 회색 칼라로 구성된다. 염색 solution의 광 흡수는 전이금속의 ion들의 에너지 분리에 의한 광흡수가 미약하게 나타나 각 색조를 구성하였다. 염색 렌즈의 광 흡수는 전이금속의 ion에 의한 에너지 분리의 광 흡수 peak가 나타나 색구성에 큰 영향을 주었다. 각 렌즈의 광 흡수 peak는 염색 시간 의존성을 갖는다. 청색칼라 렌즈는 500nm 보다 단파장에서 흡수가 크고, 이상에서는 낮게 나타났다. 황색의 경우 청색과 정반대의 광 흡수가 나타나, 녹색 칼라 렌즈의 경우 가시광 양 끝단에서 광 흡수가 크고, 중간 영역에서는 흡수가 낮았다. Pink 칼라 렌즈의 경우 녹색과 정반대의 흡수 형태로 서로 보색 관계가 나타난다. Brown 칼라 렌즈의 경우 단파장에서 최대 흡수를 갖고 장파장으로 갈수록 광 흡수가 감소한다.
