Up for sale is my Ocean Optics FLAME-S Spectrometer in EXCELLENT condition that reads from 190nm to 881nm.  This spectrometer WORKS GREAT and is super good in the UV but also VERY capable in the VIS/NIR as well.  Please notice the 6th picture featuring an Ocean Optics HG-1 mercury argon light source (mercury argon light source not included).  The spectrometer also features a L2 collection lens, #1 UV grating, a built-in second order light filter, and a 25um slit for high resolution.   The slit is the Ocean Optics user changeable slit design so it is very fast and easy to change the slit to other sizes yourself. Thank you.

If you need a great Ocean Optics VIS light source with 10,000 hour bulb, I recommend this one:
