Development of Two - beam Type Integrating Sphere Spectrophotometer and Analysis of Its Performance |
| Abstract |
A spectrophotometer using two-beam type integrating sphere is developed, and the measurement accuracy is analyzed. The efficiency of the integrating sphere is analyzed, and the relation between the efficiency and the total measurement error is found. Especially, the integrating sphere is fabricated on the basis of its characteristics according to its shape such as the sample port. The performance of the developed spectrophotometer is tested using a black and a white standard reflectance plate, and the measurement error of ±0.5% is obtained. |
