Double Monochromators, Deep UV (185nm) to IR operation

Double Monochromators include two SpectraPro monochromators used in series where the exit slit of the first “stage” is the entrance slit to the second monochromator stage. The systems are set up in an additive mode for increased dispersion and exceptional stray light rejection. The first monochromator stage disperses the spectral radiation into separate wavelength components, allowing a specific bandpass to enter the second monochromator. The second monochromator stage re-disperses the light, increasing spectral dispersion while further reducing stray light levels.
