Abstract
A spectrophotometer is provided, which comprises a receiving part diffusing an incident light, a first broadband filter group, and a detector detecting the light having passed through the first broadband filter group, in order to easily select and detect a plurality of lights having specific wavelengths, wherein the first broadband filter group comprises a first broadband filter arranged to have a first angle with respect to an incident direction of light to enable the incident light to pass through a first wavelength band, a second broadband filter arranged to have a second angle, which is different from the first angle, with respect to an incident direction of light to enable the light having passed through the first broadband filter to pass through a second wavelength band, and a first path compensation means for adjusting a path of the light having passed through the second broadband filter to be identical to a path of the light having passed through the first broadband filter, wherein the first broadband filter, the second broadband filter and the first path compensation means are arranged in series with respect to the incident direction of light. Accordingly, it is possible to increase the efficiency of the outputted light compared to the incident light, and to detect a plurality of lights having the desired specific wavelengths at the same time.
