Description:
The MSA-130 Double Additive/Subtractive Monochromator is a compact double Monochromator with enhanced functionality and low stray light.
The key feature of the MSA-130 is its unique ability to operate in both dispersion additive and subtractive dispersion modes.
The MSA-130 operation modes are changed over by manual switching of a two-position selector switch from the position “Addition” to “Subtraction” and vice versa without any additional alignment by the user. The instrument is multifunctional, compact, easy-to-use and reliable.
