Crude Raman Spectrometer

thingiverse

It works well enough to demonstrate the principle for a strong Raman emitter like polystyrene. I will have to fiddle with it to improve the sensitivity. Be careful assembling the parts with glass components - overtightening will break the glass. * The spectrometer is from [GroupGets](https://store.groupgets.com/collections/hamamatsu-sensors-accessories/products/hamamatsu-c12880ma-mems-u-spectrometer-and-breakout-board) * Laser is from [ThorLabs](https://www.thorlabs.com/thorproduct.cfm?partnumber=CPS532). Important to get one that has a narrow range of wavelength. * The filter is from Omega Filters. Just use an optical notch filter (or a longpass filter) to match the laser wave length. And adjust that mount to hold it. You can get a smaller filter - that was what was available on eBats at the time. * 5x infinity microscope objective * The square mirror was a half silvered mirror, Not critical. * i didn't really need the fan.
