Up for sale is my Ocean Optics FLAME-S Spectrometer in EXCELLENT condition.  This spectrometer WORKS GREAT and is extremely sensitive. It features a L2 collection lens, a #1 UV grating, a built-in second order light filter, and a 25um slit.  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.  I have several of these spectrometers and they are all a tiny bit different.  For example, one reads from 187nm to 879nm, one reads from 186nm to 877nm, one reads 184nm to 872nm, etc, so you will be getting one of those.  All of them are excellent in the UV.  Thank you.

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