MSA130 - Double Monochromator / Tunable Filter

The MSA-130 has the unique capability to operate in both additive and subtractive dispersion mode. With easy switching the same device can operate as low stray light double monochromator in additive mode and also as tunable and adjustable narrow bandwidth filter in subtractive mode, which makes it an ideal instrument for Raman, emission and fluorescence spectroscopy.
