Confocal Detection Principle


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.

We have created the instrument that is right for you

Biology


Raman spectroscopy allows easy visualization of cellular components with minimum perturbation.

Pharmaceutics


Confocal Raman spectroscopy allows chemical compounds and molecular conformers in various drugs to be identified and their distribution mapped with high spatial resolution.

Geology


Confocal Raman microscopy is an excellent technique for characterization of minerals, detection of components distribution and their phase transitions.

Cosmetology


Confocal Raman microspectroscopy is a promising technique which enables measuring the skin care products as well as their penetration capability.

Forensics


Application areas include identification of unknown substances, different types of fibers, glasses, paints, explosive materials, inks, narcotic and toxic substances, proof of authenticity of documents.

Material science


Confocal Raman offers excellent spatial resolution for characterization of materials (superconductor, polymers, coatings, composites, carbon nanotubes, graphene, etc.).

Heritage and Art, Gemology


Raman spectroscopy allows identification 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 identification of colored stones, natural and synthetic diamonds.

High spatial resolution and sensitivity


Major features

The highest spectral and imaging resolution with specially designed spectrometer


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.

High optical throughput for enhanced sensitivity


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.

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.

High spatial resolution


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.
