ProTrusTech is a professional Raman instrument manufacture based in Taiwan. The company was founded in 2008 and is focused on developing Raman spectroscopy systems as well as Photoluminescence (TRPL, Time-Resolved Photoluminescence), SERS (Surface-Enhanced Raman Scattering) and TERS (Tip-Enhanced Raman Scattering) solutions.

In 2010, the 3-laser Raman microscope RAMaker was launched. This was followed by the compact 1-laser Raman microscope MRIS in 2014. The MRIS has since been updated to the MRIX.

In 2016, Kagaku and Protrustech established a co-branding collaboration to promote 2017’s new Raman microscopes: MRIX and MRID. These are now available in the EU, China, India and beyond.
