Abstract
The object is to easily expand a variable range of selective wavelengths without enlarging a device. A spectral deviceof the present invention includes four band pass filterstothrough which a light Lfrom a light sourceis selectively transmitted within a wavelength range according to an incident angle of the light L, and a tabular rotary tablein which the band pass filterstoare installed upright on a principal surface, and which is made rotatable around a rotational center Calong the principal surface, and the four band pass filterstoare respectively disposed so that optical incidence planesor optical emission planesare inclined with respect to lines connecting the rotational center Con the principal surfaceof the rotary tableand center pointsandof the band pass filtersto
