摘要：
Spectrophotometry is a key area of research when it comes to analysis of optic-matter interaction. This paper shows the development of an affordable visible light spectrophotometer that can measure absorbance and transmittance of liquid solutions of various materials within the Visible range of electromagnetic spectrum. The system has a bandwidth of 72.5nm within the visible range. The instrument is verified usingKMnO(4) solutions having different concentrations. Absorbance values of the solutions are recorded and analyzed using Origin Pro 8.00 and extinction coefficient of KMnai is calculated to be 2.306 x 10(-7) Lmol(-1)cm(-1) at 525nm. Validity of this result is verified from previous researches conducted with commercial UV-Vis spectrophotometers.
