The images for left and right eyes displayed in the screen are separated by polarization filters so as to provide the 3D image. This time， regularpolarized 3D glasses (inverted V-shaped with the directions of the polarization axes crossing at 90°) were analyzed.The polarization sample measurement accessory contains 2 sample holders. Each sample holder can be rotated andthus， the transmittances of two polarization samples positioned in parallel as well as perpendicularly can bemeasured. The transmission spectra for one piece (single)， when the polarization axes of the polarization filters forright and left eyes were crossed at 90°(cross)， and when the axes were in parallel were measured. The transmittanceof the cross-position was found to be almost 0% and thus， clear 3D images can be provided. SAMPLE Sample ： Polarized 3D glasses INSTRUMENT CONDITIONS OTHER NECESSARIES Instrument ：U-4100 Spectrophotometer (solid sample measurement system) [UV/VIS1 Scan speed ： 300 nm/min Slit ： 8 nm Sampling interval ：1nm Polarization samplemeasurement accessory(P/N ： 1J0-0207)
