RAMOS N500 3D Scanning Laser Raman Microscope
Confocal Laser Scanning Raman Microscope has become a widely recognized research instrument in recent years. Confocal microscopy offers several advantages over conventional wide-field optical microscopy, including the ability to control depth of field, elimination or reduction of background information away from the focal plane and the capability to collect serial optical sections from thick samples. The image of the extended sample is generated by scanning the focused laser beam across a defined area.
The pinhole aperture rejects the residual scattered rays originated from any out-of-focus points on a sample.
High spatial resolution Raman confocal microscopy can provide information on dopant concentrations and stress distribution in semiconductor materials.
Raman spectroscopy allows easy visualization of cellular components with minimum perturbation.
Confocal Raman spectroscopy allows chemical compounds and molecular conformers in various drugs to be identified and their distribution mapped with high spatial resolution.
Confocal Raman microscopy is an excellent technique for characterization of minerals, detection of components distribution and their phase transitions.
Confocal Raman microspectroscopy is a promising technique which enables measuring the skin care products as well as their penetration capability.
Application areas include identification of unknown substances, different types of fibers, glasses, paints, explosive materials, inks, narcotic and toxic substances, proof of authenticity of x-x-x-x-x-documents.
Confocal Raman offers excellent spatial resolution for characterization of materials (superconductor, polymers, coatings, composites, carbon nanotubes, graphene, etc.).
Raman spectroscopy allows identfication of pigments and binders used in paintings. The spectroscopic analysis of archaeological samples (ceramics, glasses, etc.) provides information on their origin and history. Raman technique allows rapid identfication of colored stones, natural and synthetic diamonds.
Specially designed imaging spectrometer incorporates many features that make it ideal for confocal Raman measurements. The image of pinhole is projected to a multichannel detector without any aberrations.
The smaller amount of illuminated pixels on the CCD matrix leads to the smaller dark counts and the higher spectral resolution.
Spectral resolution of RAMOS N500 with an Echelle grating is 0.25 cm-1.
The 4th order Silicon band at 1940 cm-1 can be observed in less than one minute using a low intensity laser.
2D / 3D images can be acquired rapidly.
People with little or no experience in Raman spectroscopy can use RAMOS N500. The system is highly modular and fully automated. Up to 5 lasers can be used.
The lasers can be switched from one to another by just one click.
Motorized control for laser power, beam diameter, polarization orientation, pinhole size and grating is provided.

Low-frequency Raman shift measurement range can be expanded using Bragg notch filters.
3D scanning laser confocal Raman microscope RAMOS N500 provides the acquisition of two images within a single scan: a Rayleigh image (using laser light reflected from a sample) and a spectral image by Raman scattering.
Ultrafast imaging option allows to get confocal image in 3 sec (3 μs/pixel).
RAMOS N500 uses fast beam scanning by galvano mirrors.
Layout of galvano mirror scanner module allows mapping with no intensity losses from image center to its edges.
RAMOS N500 system can be used with a number of different detectors.
Up to three detectors can be used simultaneously. Proprietary algorithm for taking high speed of Raman imaging with fast spectral CCD (EMCCD) is offered.
The use of an EMCCD (Electron Multiplying CCD) camera can greatly increase Raman detection efficiency and speed.
Uniform, large size scanning area of a galvanic scanner module:
Automatic XY stage can be used for ultra-wide field imaging.
The panoramic image (hyper image) by automatic stitching of a series of images obtained with the use of galvanic scanner.
RAMOS N500 is equipped with a neon lamp (option) for spectral calibration.
Calibration is possible at any wavelength by one click in the control software.
RAMOS N500 software “Nano SPO” with powerful analytical functionality is designed for hardware operating, data acquisition and data analysis.
