RAMOS S120. Dual-channel automated Raman confocal microscope

RAMOS S120 compact dual-channel confocal Raman microscope is designed for micro spectral measurements with capabilities at the level of high-end systems.

RAMOS S120 microscope has a rigid, moving parts-free design that requires no adjustments, has both high sensitivity and high spatial resolution, and can be equipped with two single-mode lasers simultaneously, 488/633 nm or 532/785 nm.

Spectral measurements are provided by a highly efficient automated two-channel monochromator spectrograph.

Wide possibilities, high reliability, and compactness allow using RAMOS S120 for solving a wide range of scientific and industrial applications.

The objects for complex research can be semiconductors, minerals, polymers, pharmaceutical, and biological substances, single molecules and nanoparticles.
