    2. General The Raman spectrophotometer is a general-purpose analytical instrument used to examine both inorganic and organic substances in various fields of science. This configuration of this instrument must be optimized for different types of measurement, such as photolysis measurement, ultra-low wavenumber measurement, wide-range measurement for qualitative analysis and measurement using the resonance effect, for example. The NRS-3000 series permits the instrument configuration to be optimized easily by simple automated operations according to the purpose of measurement.

    4. Opening 3 : NRS-3100 Standard model NRS-3200 Multi-configuration model NRS-3300 Advanced applications model Within the same basic optical system, We have designed a family of Raman spectrometers That cover the spectrum from simple, single laser instruments, To advanced research grade systems with low wavenumber capability and wavelength extension From deep UV to NIR. NRS-3100 Standard model The NRS-3100 is intended as the entry-level instrument without the low wavenumber measurement, high resolution option or the dichroic mirrors. NRS-3200 Multi-configuration model The NRS-3200 is the mainstream instrument with dichroic mirrors and high-resolution options Together with a higher performance CCD. NRS-3300 Advanced applications model The NRS-3300 adds the low wavenumber measurement capability within a wider footptint baseplate.

    10. If we build up a modern version of Ramans 1928 experiment it might look something like this. Green laser light is inelastically scattered by the sample and loses some energy, so some light shifted towards longer wavelengths is produced. The dispersing system- this is usually a holographic grating in modern instruments- spectrally separates the Raman scattered light from the excitation beam before detection. Because the laser light is relatively so intense, we also further cut it out from the spectrum by either successive monochromators or an optical notch filter And in practise we illuminate the sample either using a microscope, at about 1 micron resolution, or macroscopically- macro is often used for bulk samples, liquids and gases. The microscope allows us to carry out mapping studies of the samples composition distribution.
