Barak Raman system

The Nanonics Barak microRaman is a research-level hard coupled or fiber coupled confocal Raman system that offers affordability without compromising on performance or flexibility.  The Barak takes advantage of a unique modular design that can be supplied either as a complete turnkey system or customized with a customer's own spectrometers, CCD's, and lasers.  This system is easily upgradable to Nanonics AFM-Raman and TERS systems.
