Abstract
A spectrophotometer is provided which includes: (i) a Linear Variable Filter, (ii) a linear sensor or a two-dimensional image sensor, and (iii) at least one fiber optic plate that is disposed between the Linear Variable Filter and the linear sensor or two-dimensional image sensor, and that transfers light separated into spectral components and outgoing from the Linear Variable Filter to the linear sensor or two-dimensional image sensor. With this structure, a compact spectrophotometer can be obtained which has an excellent wavelength resolution, accuracy, and light transfer ratio, and which can conduct wavelength spectral measurements at high speed and with high accuracy.
