Protrustech Raman Systems - Mrid Dual-laser Autoscan
MRID Dual-Laser Raman
2 Scans in 1 Click
MRID is a microscopic Raman identification system built in with two lasers that could instantly switch by software or automatically switch between scans at different wavelengths. This patented laser auto switch technology allows users without expertise to switch lasers any time immediately while still ensuring that the optical path for each laser stays optimised after every switch. MRID makes it unprecedentedly easy to swiftly inspect the same sample right at the same spot with any two different laser wavelengths among 473, 488, 532, 633, 785, 808 and 830 nm. Moreover, the two excitation sources could also be applied at the same time.
MRID 532/785 Dual Lasers - Scans with Auto Switch
Raman & PL in One Click
One-click to get both Raman and Photoluminescence spectra. MRID could be equipped with an excitation source for Raman spectroscopy while the other for Photoluminescence (eg. 375 or 405 nm). With the auto switch technology, both Raman and PL scans could be completed one after another automatically with one single click.
0.01 mW/step Laser Power Control
Direct laser output could be controlled at 1mW/step by software, plus a round continuously variable neutral density filter (O.D 2.0~0.04) contolled by software offering transmission from 1% to 100%, resulting in 0.01 mW/step laser power control.

Smart Raman System
Smart features keep you out of all the troubles - Laser power could be adjusted by 5 steps via ND filters as well as by 100 steps thru software control. Laser modules could be adjusted and optimised in 3 directions. Over-exposure caused by the laser beam is prevented under microscopic imaging. Laser auto sleep mode. Restorable laser parameters. Programmable batch scans, and so on and so forth.
