The Nomadic Raman microscope from BaySpec (San Jose, CA) features three excitation sources (532, 785, 1064 nm or custom), each of which has dedicated spectrographs and detectors. Coupled with micrometer spatial resolution from an optical microscope, ideal applications include biomedical research and fluorescence suppression. Customized gratings cover either the chemically informative 400–1700 cm-1 range or the full 200–3200 cm-1 range.
The Nomadic is the only Raman microscope on the market today that is simultaneously equipped with three excitation sources (532, 785, 1064 nm or custom) . The dedicated spectrographs and detectors for each excitation wavelength ensures optimal spectral coverage, resolution, and sensitivity, with no trade-offs or compromises. Coupled with micrometer spatial resolution from a research grade optical microscope, the Nomadic delivers the full power of micro Raman spectrometry with unprecedented flexibility and versatility.
The lastest product innovation in our Raman microspectroscopy line is the MovingLab, a low cost portable instrument that can be bought out into the field or used for mobile forensics work. The MovingLab can be configured with any wavelength of choice, standard are 532, 785, 1064 nm or custom.

For each excitation source there is a dedicated spectrograph and detector. All the spectrographs are equipped with a high efficiency transmission VPG that delivers unsurpassed optical throughput. The gratings are customized to either cover the chemically informative 400-1700 cm-1 range or the full 200-3200 cm-1 range. For 532 nm excitation, the detector is a 2048 element CCD array detector thermoelectrically cooled to -20 °C, while for 785 nm source the CCD array detector is thermoelectrically cooled to below -20 °C for superior signal to noise ratio in the wavelength range from 900 to 1100 nm. For 1064 nm excitation, the array detector is based on InGaAs and thermoelectrically cooled to below -50 °C to suppress dark currents from thermal noise and maximize signal relative to the noise floor.
The NomadicTM and MovingLabTM are run by BaySpec’s Micro 20/20 software that has an intuitive, streamlined user interface and can output data in .txt, .csv, or .spc format. Baseline correction function is intelligently built in, which greatly facilities reduction in fluorescence interference and account for drift in background.
