MRID (Micro Raman Identification Dual Lasers)
MRID is a microscopic Raman system inbuilt with two lasers automatically switchable by software. This design is granted a Taiwan invention patent I709732 and the corresponding USA utility patent is also under examination. It solves the trouble of optimizing the optical path each time a different laser wavelength is used, and in turn provides a highly reliable optical system that users without optical backgrounds could also handle with ease.
One click to automatically measure the spectra excited by different wavelengths is another PTT proprietary feature. This feature could also acquire both Raman and Photoluminescence signals respectively and automatically from the same excitation source.
Polarization Module :
Different alignment of optical axis with respect to the incident laser polarization can lead to different spectra
for anisotropic samples, such as strained films or crystals. The polarization feature facilitates the
observation of such properties by controlling both directions via software.
