The ATR8300Pro series combines the advantages of microscopes and Raman spectrometers. The Raman microscope detection platform makes it possible to "what you see is what you measure". The visual and precise positioning of the Raman detection platform allows observers to detect Raman signals of different surface states on the sample, and can simultaneously display the microdomain morphology of the detected location on the computer, greatly facilitates Raman microdomain detection.
The ATR8300Pro high-end version can fully auto-focus, fully auto scanning, and one-click operation. It can perform batch experiments, uniformity scanning, etc. without waiting, and can obtain highly reliable scanning imaging Raman data. Microscope objective is specially designed for the Raman system, which makes the laser spot close to the diffraction limit. It overcomes the problem that the focal plane for collecting Raman signals in ordinary Raman systems is slightly higher or slightly lower than the actual optimal focal plane, thus improving the quality of Raman spectra.
ATR8300Pro is equipped with spectrometers with different focal lengths, which can achieve an optimal spectral resolution of 0.35 cm-1. The spectrometer has multiple built-in gratings. The gratings and their rotation angles can be set by software to meet the requirements of different resolutions and different wave number ranges.
At the same time, ATR8300Pro uses high-performance Raman specially optimized for Raman microscopy systems. It is industry-leading in terms of sensitivity, signal-to-noise ratio, stability, etc., providing a strong guarantee for Raman research.
