Micro Raman Spectrum Measurement System
The micro Raman spectrum measurement system enables visual precision positioning, allowing operators to detect Raman signals from different surface states of a sample while simultaneously displaying the micro-zone status of the detected position on a computer. This greatly facilitates Raman micro-zone detection, making "what you see is what you measure" possible. By integrating an optimized confocal microscopy module with an advanced Raman measurement system, the platform combines precise optical design matched with infinity-corrected microscopic optics, optimized light path arrangements, and flexible structural modular combinations. Additionally, the high-quality lasers and spectrometers provided by CNI offer customers a wider range of options.
Features
- Adjustable laser with stable frequency, avoiding wavelength drift and damage of samples.
- Optimization of the confocal module, ensuring that focal plane of the laser and view focal plane of the objective confocal.
- Detector with high stability, improving the spectral acquisition efficiency and accuracy.
- Modular design, self-assembly, simple operation and easy to carry.
- Wavelength range and resolution can be customized.
Application
- Identify microns impurities of the pills and describe the distribution.
- Distinguish the effective active ingredient and accessories in pills. Describing the distribution and density of occurrence.
- Positioning precisely the boundary of different particles in ore or arts.
- Describing and locating material contained within mineral or rock.
- The identification of trace material evidence, such as the drug, medicine, explosives, textile and so on
