Abstract
We studied absorbance of tinted dye absorbed into tinted lenses by Spectrophotometric method. Used lenses and tinted dye were CR-39 plastic optical lenses and Ons & $Lavas^{(R)}$ Blue, respectively. Absorbance values of tinted dye absorbed into tinted lenses were obtained from the differences of absorbance values between tinted lenses and CR-30 lenses. Average concentrations of tinted dye absorbed into tinted lenses were obtained from the mass differences between tinted lenses and CR-30 lenses. The relationship between absorbance and average concentration for tinted dye absorbed into tinted lenses was also confirmed to follow Beer’s law. The absorption coefficient calculated from the tangent of the calibration curve was determined to be a=0.983 $Lg^{-1}cm^{-1}$.
분광광도법으로 칼라렌즈 내 염색제에 대한 흡광도를 연구하였다. 사용된 렌즈와 염색제는 각각 CR-39 플라스틱 광학렌즈와 Ons & $Lavas^{(R)}$의 Blue 1800 이다. 칼라렌즈 내 염색제의 흡광도는 칼라렌즈와 CR-39 렌즈의 흡광도의 차를 이용하여 구하였으며, 염색제의 평균농도는 칼라렌즈와 CR-39 렌즈의 질량차로부터 구하였다. 칼라렌즈에 침투된 염색제에 대하여도 흡광도와 평균농도 사이에 Beer 법칙이 성립하였고, 검정선의 기울기로부터 흡광계수는 a=0.983 $Lg^{-1}cm^{-1}$임을 알아내었다.
