Test of optical filters
Blue , Green and Red filters were tested in different wavelengths (400 nm - 600 nm) in a spectrophotometer. Excellent absorbance/emmitance results given by the blue and red filters near 580nm and 490nm respectively. 580nm is the wavelength where intensity of light is to be measured to identify the presence of mOrange. 490nm is the wavelength where maximum light intensity is expected with or without the presence of mOrange.
