MRID - Micro Raman Identification
The MRID is a microscopic Raman system featuring two inbuilt lasers that can be automatically switched by software. This innovative design has been granted a Taiwan invention patent (I709732) and a USA invention patent (US 11,340,114 B2). It eliminates the need to optimize the optical path each time a different laser wavelength is used, providing a highly reliable optical system that can be easily handled by users without an optical background.
Thanks to its horizontal interlace design for the optical path, the MRID system can integrate a third laser module or more. With two of the lasers built in and fixed, the additional laser module(s) can be connected via optical fiber, allowing users to swap and configure them as needed. This flexibility facilitates a wider range of applications, making the MRID system a versatile tool for various measurement needs.
the MRID system also includes a proprietary one-click feature that allows users to automatically measure the spectra excited by different wavelengths. This unique capability highlights the differences in sample behavior under varying laser wavelengths, as demonstrated by the two spectra acquired below. For instance, the silicon chip exhibits distinct behavior at 520 cm-1 and in the NIR range when excited by 785 nm and 532 nm lasers.
This versatile feature enables the MRID system to acquire both Raman and Photoluminescence signals from the same excitation source automatically and efficiently. By simplifying the measurement process, the MRID system provides users with a convenient and reliable tool for analyzing a wide range of samples under different laser excitations.

ND control : User-input & frequentiy used transmission
Laser power output could be directly controlled by software, at 1 mW/step for RGB Laser systems, one of the major laser brands used in MRID. In addition, laser power could be reduced by a round continuously variable neutral density filter (O.D 2.0~0.04) that is also controlled by software with high precision.
