| Summary: | 碩士 === 元智大學 === 光電工程學系 === 105 === In this study, the visible spectrometer was applied to use for determining the concentration of the laundry detergent. To analyze the transmittance and absorbance at the specific wavelength, the concentration of the laundry detergent can be obtained. The results showed that the transmittance variation was inversely proportional the laundry detergent concentration at the wavelength of 664 nm and 703 nm; the absorbance variation was direct proportional the laundry detergent concentration at the wavelength of 677 nm. Furthermore, the best resolution can be obtained by monitoring transmittance at 703 nm or absorbance at 677 nm, in which the resolutions were approximated of 0.00214 % and 0.00022 %, respectively.
