Compact spectrometer MSA-130

The MSA-130 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. DOUBLE MONOCHROMATOR FOR EXCELLENT STRAY LIGHT REJECTION MULTIFUNCTIONAL: ADDITIVE/DUAL DISPERSION & NON-ADDITIVE/SUBTRACTIVE DISPERSION COMPACT & COST-EFFECTIVE HIGH THROUGHPUTА The MSA-130 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. In the Additive Dispersion Mode MSA-130 operates as a standard double additive monochromator (effective focal length is 260 nm) with extremely low stray light provided by its intermediate slit. In the Subtractive Dispersion Mode MSA-130 operates as a tunable filter with adjustable band pass and sharp edge. A width of selected spectral range is set by the intermediate slit, and the central wavelength is set by synchronous turning of two identical diffraction gratings.
