Title:
MONOCHROMATOR
Document Type and Number:
Japanese Patent JP3937485
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To make a single monochromator switchable to different characteristics according to the purpose of use by constituting an incident-side light incident and emitting device and an emitting-side light incident and emitting device to the same structure.
SOLUTION: An incident-side light incident and emitting device A and an emitting-side light incident and emitting device B has the same structure formed of slits 3, 4 and convergence lenses 5, 6. In the incidence from the light incident and emitting device A, this monochromator can take much light so as to be bright since the incident-side F value is small, and it is thus suitably used as a monochromatic light source. On the other hand, in the incidence from the light incident and emitting device B, the form of luminous flux of the emitted light is substantially constant because the emitting-side F value is substantially constant, and the light emitting area within a sample in each wavelength is not changed. Therefore, it is suitable for a use such as spectral irradiation of a sample. Since the reverse light dispersion is also constant to wavelength, the band width in each wavelength is constant, and it is suitably used as wavelength variable band pass filter.
