Double monochromators are also available in both additive and subtractive models in 300-mm, 500-mm, and 750-mm configurations. Additive models feature a triple-grating turret and provide twice the dispersion of single monochromators of the same focal length. They also have the square of the stray-light rejection. Double additives are designed for high-resolution, high-purity applications. Double subtractive systems are supplied with single-grating kinematic mounts. They provide zero dispersion and an extremely pure homogenous bandpass of light at the exit. Typical applications include prefiltering of Rayleigh scattering for Raman spectroscopy and photoluminescence. Imaging subtractives can also be used with a CCD camera to spatially map spectral characteristics of a sample. All doubles can be ordered with exit ports on the first monochromator for single- spectrometer operation and dual exit ports for multiple detectors.

 

Double Monochromator or Single Monochromator Operation
ARC DSP-Series Double Monochromators can operate as independent single monochromators, expanding the potential applications and uses of this versatile instrument. Conversion is rapid and easy.
