Glas to be here and thanks admin for let me in, I heard about the OPENRAMAN project few years ago but until recent I finally recieved some funding from my university that allows me to build my own setup for my SERS study.
To make it even better, I live in China, which means I can get much cheaper components from Chinese vendors, so I upgared the laser to the CNI MGL-III-532-50mW Laser, and the grating also be upgrated to 2400/mm, still have ~$400 budgets left, so I would like to know how to further improve the performances of it?
Considering I need to use it for SERS study, my target is to improve the spectral resolution of the spectrometer, so my plan is to change the camera with a better CMOS, considering Sony IMX178 or IMX183, the IMX178 has the same sensor size as the IMX265 in FLIR BFLY-PGE-31S4M-C, but with higher resolution and smaller pixel size, while the IMX178 has bigger 1' sensor size and even higher resolution, but I'm a bit worried about the size differences, is that mean I need to change the lens as well for fully utilising the frame of the sensor? And if I do so do I need to change the base plate design as well...(that's already beyond my expertise...), or is there anything critical that I missed, please let me know in the comments.
Thanks for reading, I will update regularly about my work once I start to build.
