• ATR8800 C series micro-Raman spectrometer integrates up to 4 lasers and combines the advantages of both microscopes and Raman spectrometers. The micro-Raman detection platform makes it possible to "what you see is what you measure", and the visualization is accurate. The positioning Raman detection platform allows observers to detect Raman signals of different surface states on the sample, and can simultaneously display the micro-area morphology at the detected location on the computer, which greatly facilitates Raman micro-area detection.

• The entire ATR8800 series can perform fully automatic focusing, fully automatic scanning, and one-click operation. It can perform batch experiments, uniformity scanning, etc. without waiting, and can obtain highly reliable scanning imaging Raman data;

• ATR8800 is equipped with spectrometers with different focal lengths to meet different resolution requirements. ATR8800 is also equipped with an objective lens specially designed for the Raman system, which makes the laser spot close to the diffraction limit. The focus information is accurately and intuitively displayed on the computer through a 5 million camera. on. It overcomes the problem in ordinary Raman systems that the focal plane for collecting Raman signals is slightly higher or slightly lower than the actual optimal focal plane, thereby improving the quality of the Raman spectrum.

• ATR8800 perfectly solves the loss of optical path during camera imaging and realizes the separation of camera imaging and Raman signal collection, thereby obtaining the best signal strength. At the same time, ATR8800 uses high-performance Raman specially optimized for micro-Raman systems. It is industry-leading in terms of sensitivity, signal-to-noise ratio, stability, etc., providing a strong guarantee for Raman research.

Q: Why the 1064nm Raman can resist high fluorescence materials?
A: 1064nm belong to NIR photon has a low frequency, low energy is seldom absorbed by the sample molecule, and it's difficult to excite ground state electron as well as fluorescence, so that it prevent fluorescence from generation.

Q: Why Raman signals are easily annihilated by fluorescence?
A: Fluorescence intensity is about 10^6 times stronger than that of Raman signal. traditional Raman signals are easily annihilated by fluorescence.

Q: Which materials have high fluorescence recommended to use 1064nm Raman?
A: Such as Heroin, Fentanyl, Colour samples, Biological samples, Textiles, Bacteria, Drugs, Fuel, Petroleum samples, Vegetable oils, Explosives, Plastic.

How many methods can remove fluorescence interference?
1st, Baseline correction uses an algorithm to remove fluorescence interference.
2nd, Difference Raman uses two wavelengths of lasers (eg: 784.5nm+785.5nm) to excite samples can obtain two sets of Raman signal and calculate the difference to obtian the spectrum without fluorescence.
3rd, Time gate control method
4th Fluorescence photobleaching method
5th, 1064nm Raman spectrometer is highly recommended
