LRS-5 Chongqing Raman Spectrometer

Chongqing Raman Spectrometer Product Introduction

• LRS-5 is a micro area laser Raman spectrometer with independent intellectual property rights developed by Hong Kong East Company in participation in a major national science and technology project. The LRS-5 micro area laser Raman spectrometer uses a high-resolution confocal laser microscope with independent intellectual property rights as the system for collecting Raman scattering light, a monochromator for long focal length high-resolution flat field imaging output, and a self-developed computer software programming to construct a new high-resolution laser confocal microscopy detection device with independent intellectual property rights - the laser confocal Raman spectrometer. The product has high resolution, sensitivity, and stability, and is suitable for Raman spectroscopy measurement in scientific research institutions, universities, chemical laboratories, and physics laboratories.

Product features of Chongqing Raman spectrometer

• The first Raman spectroscopy monochromator with long focal length and high-resolution flat field imaging output in China

• *The 800mm focal length Raman spectrometer can achieve the highest spectral resolution

• High resolution spectrometer constructed with a single grating using C-T structure (focal length 800mm, grating 1800 lines/mm)

• Software automatic control

• The reflectivity of the reflector reaches 90%

• The maximum reflectivity of each grating can reach 70%

• Reduced optical components such as gratings, mirrors, and intermediate gaps, and increased the sensitivity of Raman spectroscopy instruments by more than double

• The use of high-quality Rayleigh filters and efficient gratings and mirrors requires a Raman monochromatic system with a contrast ratio of 10-14 or higher to observe the third-order and fourth-order Raman peaks of single crystal silicon, which can be detected on LRS-5

• All optical components are designed with the utmost optimization to ensure high spatial and spectral resolution that can reach diffraction limits

• Technical modifications have been made to the flat field imaging output of the spectrometer, resulting in better linear response of the spectrometer signal output

• A single grating with high optical flux and 800mm focal length combines the highest sensitivity and highest spectral resolution

• Obtaining detailed information about test samples, such as crystallinity integrity, polycrystalline and amorphous identification, stress effects, size effects, and other characteristics, makes analysis simple and intuitive

• The receiving system adopts Andor's high-sensitivity and low-noise area array CCD receiver

• The external light path system adopts a microscope produced by 0lympus company as the laser convergence and Raman light collection system, which has high efficiency and stability

• Equipped with Edge Fiter designed to reduce Rayleigh scattering intensity

Technological superiority

• Due to the weak Raman scattering of water, Raman spectroscopy is an ideal tool for studying biological samples and chemical compounds in aqueous solutions. The Raman spectrum obtained from a single scan can simultaneously cover the wavenumber range of 50cm-1-7000cm-1, allowing for analysis of both organic and inorganic compounds.

• Raman spectroscopy has clear and sharp peaks, making it more suitable for quantitative research, database searches, and qualitative studies using differential analysis. Because the diameter of the laser beam at its focal point is usually only 0.2mm-2mm, conventional Raman spectroscopy only requires a small amount of sample to obtain. This is a significant advantage of Raman spectroscopy over conventional infrared spectroscopy. Moreover, the Raman microscope objective can further focus the laser beam to 2 microns or even smaller, allowing for analysis of samples with smaller areas.
