Double Additive/Subtractive Monochromator
doubleadditive

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.

Features:

  • Double Monochromator for Excellent Stray Light Rejection
  • Multifunctional: additive/dual dispersion & non-additive/subtractive dispersion
