MONOCHROMATOR USING OPTICAL FILTERS TO SELECT WAVELENGTH OF LIGHT

摘要

Provided is a monochromatization device for easily selecting light having a specific wavelength, comprising: a first broadband filter arranged to have a first rotational angle with respect to an incident direction of light to enable a first wavelength band to pass therethrough with respect to the incident light; a second broadband filter arranged to have a second rotational angle with respect to an incident direction of light to enable a second wavelength band to pass therethrough with respect to the light passing through the first broadband filter; and a path compensation unit for adjusting a light path so that the light path passing through the second broadband filter is the same as a path of the light incident to the first broadband filter. Accordingly, the output light efficiency for the incident light is increased and the required specific wavelength can be more easily selected.

1. A monochromatization device for selecting a specific wavelength of light, comprising:
a first broadband filter arranged to have a first rotational angle with respect to an incident direction of light to enable an incident light to pass through a first wavelength band; a second broadband filter arranged to have a second rotational 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 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.
