We are a small startup company in Istanbul working on wearable technologies. And specialize in optics research
We need a working engineering model for the design proposed in the following article
A miniature confocal Raman probe for endoscopic use 
The design can be found in figure 3
We need a fully working simulation for both input coupling from the optical fiber, collections optics and simulations for different wavelengths.
Expected are a COMSOL file, CAD files, relevant plots.
