Detail

Description:

Optosky ATR8300 Raman microscope combines benefits of microscope and Raman spectrometer. It becomes possible to see macro or micro areas of samples on the computer screen with just a single mouse click. When accurate positioning is visualized, the observer can detect Raman signals under various surface conditions, and synchronized Mapping can be displayed intuitively on the screen at one click operation. As a result, it provides great convenience to detect micro or macro areas of samples. Combine unique patented conjugate focusing(true confocal) system with accurate image processing algorithm, and it enables a very small sample areas to be analyzed, as well as it requires minimal operator training and maintenance, yet resulting in uniform result not just spectra.

ATR8300 is equipped with tailor-made objective, and laser spot on the sample becomes very close to diffraction limit, then focal information can be displayed in accurate and intuitive on the screen with 3-megapixel camera. This configuration improves Raman spectral quality for overcoming the limitations of Raman systems where the focal plane for Raman signal collection is slightly above or below the imaging plane.

ATR8300 works very stable with no moving components of optical path switch, hence it avoids loss off optical path while imaging formed, and it gains optimized signal for separating imaging formed from Raman signal collection.
